Specification
Benzamide,4-amino-, its cas register number 2835-68-9. It also can be called p-Aminobenzamide ; and 4-Aminobenzamide .
Benzamide,4-amino- (CAS NO.2835-68-9) could be stable. It should avoid the condition like incompatible materials, exposure to moist air or water. It is not compatible with strong oxidizing agents, strong acids. And also prevent it to broken down into hazardous decomposition products: hydrogen cyanide, carbon monoxide, oxides of nitrogen, carbon dioxide, nitric acid. However, its hazardous polymerization will not occur.
