3-Hydroxy-4-methylbenzoic acid(CAS: 586-30-1)

3-Hydroxy-4-methylbenzoic acid (CAS: 586-30-1) is a crystalline solid with a molecular weight of approximately 154.17 g/mol. It has a pKa of about 3.0 and is slightly soluble in water but more soluble in organic solvents like ethanol and acetone. The compound is reactive towards basic conditions and undergoes esterification and condensation reactions.

3-Hydroxy-4-methylbenzoic acid can be synthesized via a two-step process. First, 4-methylbenzoic acid is converted to its methyl ester using methanol and an acid catalyst like sulfuric acid. Then, the methyl ester undergoes hydrolysis under basic conditions to yield 3-hydroxy-4-methylbenzoic acid. This method provides a yield of about 85%.

3-Hydroxy-4-methylbenzoic acid is primarily used in the pharmaceutical industry for the synthesis of certain drugs. It also has applications in the polymer industry as a monomer and in the production of sensors and semiconductors for electronic devices.

When handling 3-Hydroxy-4-methylbenzoic acid (CAS: 586-30-1), wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. Store it in a fume hood or a well-ventilated area, and use proper spill cleanup procedures. Refer to the Safety Data Sheet (SDS) for detailed information on handling and disposal.
