3-cyanobenzoic acid(CAS: 1877-72-1)

3-Cyanobenzoic acid (CAS: 1877-72-1) is a white crystalline solid with a molecular weight of 163.12 g/mol. It has a solubility of 1.2 g/100 mL in water at 25°C. The compound is moderately reactive with bases and reduced reactivity with acids. It exhibits weak acid properties and can form salts with bases.

3-Cyanobenzoic acid is typically synthesized by the reaction of benzoic acid with nitrogen trichloride (NCl3) or by the nitration of benzoic acid followed by hydrolysis. The nitration step yields 2,4,6-trinitrobenzoic acid, which is then reduced to 3-cyanobenzoic acid using various methods such as copper catalysis or hydrogenation.

3-Cyanobenzoic acid (CAS: 1877-72-1) is used in various industries. It is a crucial intermediate in the synthesis of pharmaceuticals, particularly in the production of anti-inflammatory and analgesic drugs. It is also used in the production of dyes, as a precursor for the synthesis of polymers, and in the development of sensors and semiconductors.

When handling 3-cyanobenzoic acid (CAS: 1877-72-1), appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat should be worn. The compound should be stored in a tightly sealed container in a cool, dry place away from direct sunlight. In case of a spill, it should be cleaned up using appropriate procedures as outlined in the material safety data sheet (MSDS/SDS). Work should always be conducted in a well-ventilated area or fume hood due to its potential for forming corrosive vapors.
