Description

(β-,4-Dihydroxyphenethyl)Methylammonium Hydrogen [R-(R*,R*)]-Tartrate is a high-purity, chiral organic salt primarily used as a key intermediate in advanced pharmaceutical synthesis and fine chemical manufacturing. Its value lies in its specific stereochemistry and functional groups, which are critical for producing enantiomerically pure compounds with targeted biological activity. This product is essential for R&D laboratories and production facilities in the pharmaceutical, agrochemical, and specialty chemical industries seeking reliable, high-quality building blocks for complex molecule assembly.

Application

• Pharmaceutical Intermediate: A crucial chiral building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in neurological and cardiovascular drug research.
• Asymmetric Synthesis: Used as a resolving agent or chiral auxiliary in stereoselective chemical reactions to produce single-enantiomer products.
• Biochemical Research: Serves as a precursor or standard in the study of catecholamine pathways and related biochemical processes.
• Fine Chemical Production: Employed in the manufacture of advanced ligands, catalysts, and other specialty chemicals requiring high stereochemical purity.
• Agrochemical Development: Acts as an intermediate in the synthesis of novel, enantiomerically pure pesticides and herbicides.
