Ahr 376 Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. Human systemic effects by ingestion: hallucinations, distorted perceptions, and toxic psychosis. When heated to decomposition it emits toxic fumes of NOx and HCl.

Ahr 376 Specification

 Production methods of Ahr 376 (CAS NO.13118-10-0) is potassium permanganate oxidation of styrene to produce phenyl acid, then with the participation of methanol in sulfuric acid esterification was acetophenone methyl ester, the latter with cyclopentadiene Addition (Grignard reaction, the first metal magnesium, anhydrous ether, ethyl bromide Grignard reagent is made), with α-cyclopentadienyl mandelic acid methyl ester, and thus the activity of nickel-catalyzed hydrogenation under pressure and finally with the N-methyl-pyrrolidine -3 - alcohol ester exchange obtained the goods. Ahr 376 (CAS NO.13118-10-0) can be used as a intermediate product of stomach Changning.

 It is a high-toxic products, with flammable, while burning it would release of toxic nitrogen oxides and hydrogen chloride fumes, and should be stored in ventilated ,low-temperature, drying environment,besides should be kept separate with food and raw materials , dry powder, foam, sand, carbon dioxide, water mist fire-extinguishing agent can be used if emergency.
