Description

Benzeneacetic Acid, 4-(3-Methylbutyl)- (9Ci) is a specialized organic acid derivative with a branched alkyl chain substitution on the phenylacetic acid core. This structural feature makes it a valuable intermediate and building block in fine chemical synthesis, offering a unique combination of aromatic and aliphatic properties. It is primarily sought by pharmaceutical, agrochemical, and fragrance research and development sectors for creating novel compounds. Its CAS number is 14377-20-9.

Application

• Pharmaceutical Intermediate: A key synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly those requiring lipophilic aromatic-acid motifs.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where its specific structure can influence bioavailability and activity.
• Fragrance and Flavor Chemistry: Serves as a precursor for esters and other derivatives that contribute to complex aromatic profiles in perfumery and flavoring agents.
• Organic Synthesis Building Block: Employed in academic and industrial research for constructing more complex molecules via reactions at the carboxylic acid or aromatic ring.
• Liquid Crystal and Polymer Research: Potential monomer or additive for specialty polymers and advanced materials due to its rigid and flexible molecular segments.
