4. Application Cases

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.

Case 2: Herbicide Production

Used in the synthesis of Chlorpropham (herbicide) by reacting with isopropyl chloroformate under controlled pH (8-9) and temperature (40-50°C).

Case 3: Pharmaceutical Intermediate

Serves as a precursor for anticonvulsant drugs. A two-step process involving acetylation and cyclization yields the active compound.
