What is Fenpyrazamine?

Plain description, key identifiers and synonyms

Fenpyrazamine is a pyrazolone that is pyazol-3-one which is substituted at positions 2, 4, and 5 by isopropyl, o-methylphenyl, and amino groups, respectively, and in which the hydrogen attached to the nitrogen at position 1 is replaced by an S-allyl carbothioate moiety. A fungicide, it is used for the control of Botrytis in the greenhouse cultivation of tomatoes, peppers, and cucumbers. It has a role as a sterol biosynthesis inhibitor and an antifungal agrochemical. It is a primary amino compound, a thioester and a pyrazolone.
