4. Casos de aplicação
Case 1: Dye Intermediate Synthesis
3-Chloroaniline is reacted with nitrous acid to form diazonium salts, which couple with naphthol derivatives to produce heat-resistant azo dyes for textiles.
Caso 2: Produção de herbicidas
Used in the synthesis of Chlorpropham (herbicide) by reacting with isopropyl chloroformate under controlled pH (8-9) and temperature (40-50°C).
Caso 3: Intermediário farmacêutico
Serves as a precursor for anticonvulsant drugs. A two-step process involving acetylation and cyclization yields the active compound.
