Application
5-Amino-2-methylbenzoic acid (5-Amino-o-toluic acid, CAS 2840-04-2) is a high-purity, functionalized benzoic acid derivative utilized as a key pharmaceutical intermediate in targeted drug discovery. This versatile heterocyclic building block is a critical precursor for synthesizing dihydroxylphenyl amides as potent Hsp90 inhibitors and 2,5-diaminopyrimidine derivatives as selective Bruton’s tyrosine kinase (BTK) inhibitors for oncology research. It also serves as Nilotinib Impurity 46, an essential reference standard for analytical method development, quality control, and ANDA filings. In pharmaceutical R&D, this scaffold enables rapid construction of anti-inflammatory, antimicrobial, and antiviral drug candidates. Its amino and carboxylic acid groups allow amide coupling and further functionalization for structure-activity relationship studies. Additionally, it is used in dye synthesis, agrochemical development, and as a monomer for high-performance polymers and coordination polymers. High purity ensures reproducible results in high-throughput screening and scalable GMP manufacturing.
