CAS 3970-35-2 — 2-Chloro-3-nitrobenzoic acid

2-Chloro-3-nitrobenzoic acid is an aromatic carboxylic acid featuring a chlorine substituent at the 2-position and a nitro group at the 3-position, primarily used as an intermediate in organic synthesis, pharmaceuticals, and agrochemical production. It serves as a key building block for dyes, pesticides, and fine chemicals due to its reactive functional groups. This chemical has a CAS number of 3970-35-2, is non-hazardous (no signal word), and is typically supplied as a white to off-white crystalline solid. It is stable under normal conditions but should be stored in a cool, dry place away from moisture and strong oxidizing agents. Molekula supplies 2-Chloro-3-nitrobenzoic acid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
