Specification

Diaminomaleonitrile(CAS NO.1187-42-4) is also named as 2,3-Diaminomaleonitrile; CCRIS 921; Hydrogen cyanide tetramer; NSC 266758; 2-Butenedinitrile, 2,3-diamino-, (2Z)-; 2-Butenedinitrile, 2,3-diamino-, (Z)- (9CI). Diaminomaleonitrile is brown crystalline powder. It is sensitive to prolonged exposure to air. Flash point data are not available for Diaminomaleonitrile, but it is probably combustible. It is widely used in the field of synthetic medicine, microorganism culture, condiment, pesticide, dyes, pigments and so on. It is a kind of organic intermediates using extensively.
