1. Pharmaceutical synthesis: As an intermediate for β-lactam antibiotics, carboxylic acid groups are built through hydrolysis of cyano groups.
2. Pesticide industry: Reduction of nitro groups to amino groups and synthesis of aniline herbicides or pyrethroid pesticides.
3. Dye synthesis: Used to prepare azo dyes, with color fastness of 4-5.
4. Materials Science: As a comonomer to improve the heat resistance of polymers (glass transition temperature ≥280℃).
storage requirements
Environment: Cool, ventilated and dry warehouse, away from fire sources and oxides.
● Protection: Wear N95 mask, goggles and chemical protective gloves when operating.
Safety measures: Use clean tools to collect leaks and place them into closed containers to avoid dust.
