Killion, D. D.; Frans, Robert E. published an article about the compound: 2,3,5-Trichloropyridin-4-ol( cas:1970-40-7,SMILESS:OC1=C(Cl)C(Cl)=NC=C1Cl ).Quality Control of 2,3,5-Trichloropyridin-4-ol. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:1970-40-7) through the article.

The effect of pyriclor, as well as carbonyl cyanide m-chlorophenyl hydrazone, 2,4-dinitrophenol, and oligomycin, on O uptake and oxidative phosphorylation was investigated with mitochondria isolated from hypocotyls of etiolated soybeans (Glycine max var Lee). Pyriclor inhibited both coupled and uncoupled reactions. This suggests that pyriclor either acts on a nonphosphorylating intermediate close to the electron carrier chain or with a component of the electron carrier chain, or both.

Although many compounds look similar to this compound(1970-40-7)Quality Control of 2,3,5-Trichloropyridin-4-ol, numerous studies have shown that this compound(SMILES:OC1=C(Cl)C(Cl)=NC=C1Cl), has unique advantages. If you want to know more about similar compounds, you can read my other articles.

The effect of pyriclor on some photochem. reactions that bring about the formation of assimilatory power, the generation of ATP and NADPH, at the expense of radiant energy was determined by using isolated Spinacia oleracea var Viroflay (spinach) chloroplasts. The assimilation of CO2 and cyclic photophosphorylation catalyzed by FMN both showed inhibition at a rather high level of pyrichlor; however, O evolution and noncyclic photophosphorylation were strongly inhibited. Evidence is presented to support the conclusion that the locus of attack is the O-evolving system and (or) Pigment System 2 of the photosynthetic apparatus

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Differential response of ditchbank grasses to herbicides, published in 1973, which mentions a compound: 1970-40-7, mainly applied to grass control herbicide; dalapon grass control; amitrole grass control; pyriclor grass control, Electric Literature of C5H2Cl3NO.

The undesirable plants reed canarygrass, quackgrass, and smooth brome were consistently more susceptible to 3-amino-s-triazole-ammonium thiocyanate (amitrole-NH4SCN) [51365-94-7] than were 3 desirable short grasses Kentucky bluegrass, creeping red fescue, and redtop. Reed canarygrass and redtop were more susceptible to dalapon [75-99-0] than was creeping red fescue. Amitrole-NH4SCN-dalapon mixture in various combinations was more toxic to reed canarygrass, smooth brome, and redtop than to creeping red fescue. Pyriclor (I) [1970-40-7] was quite toxic to all the grasses, with Kentucky bluegrass showing the most tolerance. Trichloroacetic acid-amitrole-NH4SCN mixture was similar in activity to the mixture with dalapon, but had less overall toxicity.

A major problem in mech. harvesting of cotton is to efficiently remove or desiccate the leaves and inhibit further growth. The major areas of study are: defoliation, desiccation, regrowth inhibition, wilt agents, and effects of harvest-aid chem. on boll weevils. Various chem. agents were tested against amitrole as control. Pyrichlor was most active as regrowth inhibitor when applied at 0.5 to 0.7 5 lb/acre, about half that of amitrole. Paraquat increased the defoliant activity of Def and Folex. GC 7887 is a promising defoliant. Defoliants had little effect on weevil numbers, whereas desiccants decreased the number of weevils, probably because they reduced the food supply. Chem. residues were not detected after 5 months in treated soil or seed samples.

2,3,5-Trichloro-4-pyridinol (Daxtron) (I) is a white, solid, highly stable compound, m. approx. 216°. Solubilities in g. per 100 g. solvent at 23° are: H2O 0.057; acetone 4.0; benzene 0.071; EtOH (95%) 4.21; xylene 0.30; NaOH (1%) 5.35. Vapor pressures at 26° and 50° are 5.50 × 10-6 and 1.39 × 10-4 mm. Hg, resp. I, normally used as the K salt, was absorbed by both roots and foliage and was especially effective for the control of grasses, though it also controlled many broadleaf weeds. Used in noncrop situations at early postemergence, 1.25 lb. I/acre controlled for one season. Against more mature broadleaf vegetation, I (2.5 lb.) plus Tordon (4-amino-3,5,6-trichloropicolinic acid) (1 lb.) was more effective. Orchardgrass, broomgrass and quackgrass were completely controlled by I at 6 lb./acre. Under more humid conditions higher dosages were required. Granular forms could also be used, especially preemergence. Preliminary crop trials in sugarcane gave promising control at <2 and in corn at 0.25-0.75 lb./acre.

SDS of cas: 1970-40-7. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms.

Weed control performance of several herbicides, their effects on tobacco (Nicotiana tabacum), and 2 methods of soil incorporation were studied in North Carolina in 1967 and 1968. Herbicides which gave acceptable weed control without injuring tobacco or lowering its quality were 4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline (nitralin), 1,1,4-trimethyl-6-isopropyl-5-indanyl ethyl ketone (D 497), Me 3-amino-2,5-dichlorobenzoate (amiben), N-butyl-N-ethyl-α,α,α-trifluoro-2,6-dinitro-p-toluidine (benefin), S-propyl butylethylthiocarbamate (pebulate), S-propyl dipropylthiocarbamate (vernolate), N,N-dimethyl-2,2-diphenylacetamide (diphenamid), dimethyl tetrachloroterephthalate (DCPA), 2,3,5-trichloro-4-pyridinol (pyriclor), and 2-(α-naphthoxy)-N, N-diethylpropionamide (R 7465). Soil incorporation of benefin, pebulate, and benefin + vernolate with a power-driven rotary cultivator gave superior weed control compared to incorporation by disking 4 times. Significant early-season stunting of tobacco plants was observed both years in plots where benefin (1.12 or 2.25 lb/acre), benefin + vernolate (0.75 + 1.5 lb/acre), or benefin + pebulate (1.12 + 4.0 lb/acre) was incorporated by disking. No stunting was observed where incorporation was with the rotary cultivator except for benefin at 2.25 lb/acre. Neither yield nor quality of the crop was reduced.

This literature about this compound(1970-40-7)SDS of cas: 1970-40-7has given us a lot of inspiration, and I hope that the research on this compound(2,3,5-Trichloropyridin-4-ol) can be further advanced. Maybe we can get more compounds in a similar way.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Plant Physiology called Inhibition of carotenoid synthesis as a mechanism of action of amitrole, dichlormate, and pyriclor, Author is Burns, Earl R.; Buchanan, Gale A.; Carter, Mason C., which mentions a compound: 1970-40-7, SMILESS is OC1=C(Cl)C(Cl)=NC=C1Cl, Molecular C5H2Cl3NO, Recommanded Product: 2,3,5-Trichloropyridin-4-ol.

Amitrole (3-amino-s-triazole (I), dichlormate (3,4-dichlorobenzyl methylcarbamate (II), and pyriclor (2,3,5-trichloro-4-pyridinol) (III) inhibited normal carotenogenesis in etiolated wheat (Triticum aestivum) seedlings; carotenoid precursors accumulated in treated plants. In II-treated plants, ζ-carotene accumulated, whereas phytofluene, phytoene, and ζ-carotene accumulated in I- and III-treated plants. None of these herbicides interfered with protochlorophyllide synthesis or its conversion to chlorophyllide when etiolated plants were illuminated. Chlorophyll accumulated in treated plants exposed to light at 60 foot candles, but was unstable and partially destroyed by illumination at 4000 foot candles. This suggested that the phytotoxicity of these herbicides was due to inhibition of carotenoid synthesis and to consequent photodestruction of chlorophyll and of chloroplast disruption.
