5-bromo-2,4-dimethylbenzoic acid; CAS No.: 842136-27-0; 5-bromo-2,4-dimethylbenzoic acid. PROPERTIES: 5-Bromo-2,4-dimethylbenzoic acid has molecular formula C9H8BrO2, corresponding to a molecular weight of 248.06 g/mol. It appears as a white crystalline powder with a melting point between 185-188 C. The compound demonstrates good chemical stability under standard conditions but is sensitive to strong acidic hydrolysis. Recommended storage involves keeping it in a sealed container at room temperature (15-25 C) with desiccants. Safety assessments indicate it may cause eye irritation and has a pH around 3.5 (1% aqueous solution). The compound has a pKa value of approximately 3.8 for the carboxylic acid group and exhibits moderate aqueous solubility. APPLICATIONS: This 5-bromo-2,4-dimethylbenzoic acid is extensively used in the synthesis of antimicrobial agents. Its bromo-dimethylbenzoic acid structure provides a platform for developing antibacterial agents targeting bacterial dihydrofolate reductase. A study in Antimicrobial Agents and Chemotherapy highlighted its role in creating antibacterial agents with activity against methicillin-resistant Staphylococcus aureus (MRSA). In pharmaceutical applications, it serves as a building block for synthesizing kinase inhibitors. The bromo and methyl groups provide steric and electronic effects beneficial for optimizing kinase hinge binding. Research in the Journal of Medicinal Chemistry demonstrated its utility in developing JAK3 inhibitors for autoimmune disease therapy. Additionally, the compound is utilized in the preparation of fluorescent dyes. The carboxylic acid group provides a site for installing fluorescence tags, enabling detection of nucleic acid hybridization events, as reported in Chemical Communications.
