Description

o-Toluic Acid CAS NO 118-90-1 is a versatile aromatic carboxylic acid derivative of toluene, characterized by the methyl and carboxyl groups positioned ortho to each other on the benzene ring. This specific isomer is a crucial high-purity intermediate in fine chemical synthesis, valued for its role in constructing more complex molecular architectures. It is primarily sought by manufacturers in the pharmaceutical, agrochemical, and dye industries for producing active ingredients, herbicides, and pigments.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of various active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection chemicals.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other organic colorants.
• Polymer Industry: Acts as a modifier or comonomer in the production of specialty polymers and resins.
• Organic Synthesis: Employed in research and development for creating complex organic compounds, including ligands and catalysts.
• Chemical Research: Used as a standard or reagent in analytical and synthetic chemistry laboratories.
