On September 25, 1975, Serban, Alexander published a patent.HPLC of Formula: 58142-46-4 The title of the patent was Isoquinolines. And the patent contained the following:
Substituted isoquinolines (I, where R1, R3, R4, R5, R6, R7 and R8 = H, alkyl, halo, nitro, amino, mono- and dialkyl substituted amino, mono- and diaryl substituted amino, acyl substituted amino, cyano, arylthio, alkylthio, and salts of these compounds) were prepared and are effective in controlling or eradicating undesired vegetation, insects, acarina, or fungi. Thus, 4-bromo-5-nitroisoquinoline (I) [58142-46-4], prepared by nitration of 4-bromoisoquinoline [1532-97-4], showed fungicidal activity. The experimental process involved the reaction of 4-Bromo-5-nitroisoquinoline(cas: 58142-46-4).HPLC of Formula: 58142-46-4
The Article related to fungicide isoquinoline derivative, herbicide isoquinoline derivative, acaricide isoquinoline derivative, insecticide isoquinoline derivative, isoquinoline derivative pesticide and other aspects.HPLC of Formula: 58142-46-4
