Description

Benzenepropanoic Acid, -Ba--Hydroxy--α-,4-Dimethyl-, Ethyl Ester, (-α-S,-Ba-R)- (9Ci) is a high-purity, stereochemically defined chiral compound. This specific enantiomer is of significant value in advanced organic synthesis, particularly for the development of pharmaceuticals and fine chemicals where precise molecular configuration is critical. It serves as a key chiral building block or intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to produce enantiomerically pure active ingredients.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the research and development of novel Active Pharmaceutical Ingredients (APIs), especially in therapeutic areas requiring high stereoselectivity.
• Asymmetric Synthesis: Used as a starting material or reagent in catalytic asymmetric reactions to construct complex molecules with defined stereocenters.
• Agrochemical Research: Serves as a precursor in the synthesis of chiral pesticides, herbicides, or plant growth regulators where biological activity is enantiomer-specific.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, fragrances, and advanced materials that require enantiomeric purity.
• Academic & R&D Laboratories: A valuable compound for methodological studies in organic chemistry, catalysis, and medicinal chemistry.
