Description

(S)-2-(3,4,5-Trimethoxyphenyl)Butyric Acid is a high-purity chiral intermediate of significant importance in advanced organic synthesis. This compound is valued for its role as a key building block in the development of active pharmaceutical ingredients (APIs) and other fine chemicals. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for the synthesis of complex, optically active molecules.

Application

• Pharmaceutical Intermediate: A critical chiral building block for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and anti-cancer research.
• Agrochemical Synthesis: Used in the research and development of advanced, optically pure pesticides and herbicides.
• Asymmetric Catalysis Research: Serves as a valuable substrate or ligand precursor in academic and industrial research focused on developing new catalytic methodologies.
• Fine Chemical Production: Employed in the manufacture of other specialty chemicals requiring the (S)-configured butyric acid moiety with a trimethoxyphenyl group.
• Reference Standard: Used as an analytical standard in quality control laboratories for method development and validation.
