2-Chloroaniline (o-Chloroaniline) is a halogenated aniline derivative widely used as a key intermediate in dye manufacturing (e.g., azo dyes like Permanent Yellow R) and agrochemical synthesis. This compound exhibits a characteristic ammonia-like odor with a boiling point of 208-209°C, melting point of -1.94°C, and density of 1.213 g/cm³ (20°C). It is sparingly soluble in water (5.13 g/L at 20°C) but miscible with organic solvents. As a toxic substance (GHS Category 2), it requires strict handling precautions including chemical-resistant PPE and ventilation due to risks of methemoglobinemia and potential bladder carcinogenicity. Storage should be in tightly sealed containers under inert atmosphere to prevent oxidation.
