Description

(R)-(α-Cyano-4-Methoxybenzyl)Ammonium Hydrogen [R-(R*,R*)]-Tartrate is a high-purity chiral ammonium salt of a tartaric acid derivative. This compound serves as a critical chiral resolving agent and intermediate in the synthesis of enantiomerically pure pharmaceuticals and fine chemicals. It is essential for research and production in the pharmaceutical, agrochemical, and advanced materials sectors where precise stereochemistry is paramount for product efficacy and safety.

Application

• Chiral Resolution Agent: Used for the separation of racemic mixtures of acids, amines, and other chiral compounds in pharmaceutical development.
• Pharmaceutical Intermediate: A key building block in the asymmetric synthesis of active pharmaceutical ingredients (APIs), particularly for cardiovascular and central nervous system drugs.
• Catalyst Precursor: Employed in the preparation of chiral catalysts for enantioselective synthesis reactions.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Analytical Standard: Serves as a reference standard in HPLC and other chromatographic methods for method development and quality control.
• Academic & Industrial Research: A valuable reagent for methodological studies in organic chemistry and process development.
