3-Methylsalicylic Acid
3-Methylsalicylic Acid (CAS: 83-40-9) is a substituted salicylic acid supplied as a white to off-white crystalline powder.
The hydroxyl group sits ortho to the carboxyl, while the methyl group occupies the remaining ring position, so the compound is ready for diazotisation-free coupling reactions and for chelation chemistry with metal ions.
Commercial assay is 99% with low sulfated ash, and the product is packed in bags or drums for dye and dye-intermediate manufacture.
• Azo dye intermediates: a coupling component for metallised and chrome dyes.
• Pigment synthesis: used to build hydroxy-substituted colour bodies and lake pigments.
• Pharmaceutical intermediates: a precursor to substituted salicylates and benzoxazines.
• Analytical chemistry: a chelating ligand for metal determination and separation.
