Acronycine Safety Profile

Moderately toxic by ingestion and intraperitoneal routes. Questionable carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Acronycine Specification

Reactivity Profile Amines, like Acronycine (CAS NO.7008-42-6), are weak chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
Health Hazard: When heated to decomposition Acronycine (CAS NO.7008-42-6) emits toxic fumes.
Fire Hazard: Flash point data for Acronycine (CAS NO.7008-42-6) are not available. Acronycine (CAS NO.7008-42-6 is probably combustible.
