Description

2-Methylphenylacetic Acid (CAS NO 644-36-0) is a versatile aromatic carboxylic acid derivative that serves as a critical building block in advanced organic synthesis. Its value lies in its ability to introduce the ortho-tolylacetic acid moiety, a key structural feature for modulating the physical and biological properties of target molecules. This compound is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries who require high-purity intermediates for the production of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where the methylphenyl group enhances bioactivity.
• Fine Chemical Production: Serves as a building block for fragrances, dyes, and liquid crystal materials.
• Organic Synthesis & Research: Employed in academic and industrial R&D for constructing complex molecules, including ligands for catalysis.
• Chemical Reference Standard: Utilized as a high-purity analytical standard for quality control and method development in analytical laboratories.
