2,4-Dimethoxybenzoic acid(CAS: 91-52-1)

2,4-Dimethoxybenzoic acid (CAS: 91-52-1) is a white or off-white crystalline solid. The molecular weight is approximately 184.18 g/mol. It is slightly soluble in water but more soluble in organic solvents. Chemically, it is moderately reactive, particularly with bases and nucleophiles. It can undergo esterification, amide formation, and other reactions typical of carboxylic acids.

2,4-Dimethoxybenzoic acid is typically synthesized through the nitration of m-dimethylphenol followed by reduction of the nitro group. A common method involves reacting m-dimethylphenol with nitric acid in the presence of sulfuric acid as a catalyst. The nitro group is then reduced to an amino group using sodium borohydride, followed by oxidation to the carboxylic acid group.

2,4-Dimethoxybenzoic acid (CAS: 91-52-1) is used in various industries. It is a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihistamines and analgesics. It also finds applications in the polymer industry for the development of new materials, and in the production of sensors and semiconductors due to its unique chemical properties.

When handling 2,4-Dimethoxybenzoic acid (CAS: 91-52-1), it is important to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. Handle in a well-ventilated area or under a fume hood to avoid inhalation of dust or vapors. Spills should be handled carefully, collected, and disposed of according to local regulations. Always consult the Safety Data Sheet (SDS) for specific handling and disposal instructions.
