4-Chloro-2-methylbenzoic acid(CAS: 7499-07-2)

4-Chloro-2-methylbenzoic acid (CAS: 7499-07-2) is a crystalline solid with a molecular weight of 175.58 g/mol. It has a pKa of approximately 3.4 and is sparingly soluble in water at room temperature. Chemically, it is reactive towards bases and can undergo substitution reactions. It is insoluble in most organic solvents except for those with strong hydrogen bonding capabilities.

4-Chloro-2-methylbenzoic acid is typically synthesized through the reaction of 2-methylbenzoic acid with chlorine gas in the presence of a catalyst such as aluminum chloride. This process involves electrophilic aromatic substitution and requires careful temperature control to achieve high yield and selectivity.

4-Chloro-2-methylbenzoic acid (CAS: 7499-07-2) is primarily used in the pharmaceutical and chemical industries. It serves as a precursor in the synthesis of various organic compounds and is also utilized in the production of certain dyes and pigments. Its applications extend to the polymer and semiconductor industries as well, where it is used in the development of photoresists and other specialized materials.

When handling 4-Chloro-2-methylbenzoic acid (CAS: 7499-07-2), it is important to use personal protective equipment (PPE) such as gloves and goggles. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure to vapors. Spills should be cleaned up with caution using absorbent materials, and the area should be flushed with water. Always refer to the Safety Data Sheet (SDS) for comprehensive guidelines on handling and storage.
