GHS Hazard Classification

Reported hazard statements	H301, H311, H331 (78.9%), H319 (81.4%), H341 (62.3%), H373 (93.6%), H400 (93.6%), H410 (99.5%)

Documented Uses

• Dye intermediate, standards for colorimetric apparatus, manufacture of petroleum solvents and fungicides.
• Production is by low-pressure hydrogenation of 2-chloronitrobenzene with noble metal and/or noble metal sulfide catalysts at temperatures of about 50-100 °C in inert organic solvents.
• O-Chloroaniline (Class: Other Substances, Added Date: 10-1998)
• The compound is absorbed through the intact skin. o-Chloroaniline is absorbed by oral, inhalation, or dermal exposure.
• o-Chloroaniline in rabbits is metabolized to 2-amino-3-chlorophenol and 4-amino-3-chlorophenol. In soya beans it yields o-chloroaniline-n-glucoside. /from table/
• Bacillus firmus was isolated and transformed 2-chloroaniline almost quantitatively into 4-chloroacetanilide with smaller amount of 4-chloropropionanilide according to co-metabolic reaction.
