Description

(R)-[1-(Hydroxymethyl)Propyl]Ammonium Hydrogen [R-(R*,R*)]-Tartrate is a high-purity chiral organic salt, specifically the tartrate salt of (R)-2-amino-1-butanol. This compound matters as a critical chiral resolving agent and building block for the synthesis of enantiomerically pure pharmaceuticals and fine chemicals. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high optical purity intermediates for asymmetric synthesis and chiral separations.

Application

• Chiral Resolution Agent: Used for the separation of racemic mixtures of acids and other chiral compounds via diastereomeric salt formation.
• Pharmaceutical Intermediate: Serves as a key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs) requiring specific (R)-configuration.
• Asymmetric Synthesis Catalyst/ Ligand Precursor: Utilized in the preparation of chiral ligands for metal-catalyzed asymmetric reactions.
• Agrochemical Synthesis: Employed in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Acts as a building block for high-value chiral compounds used in flavors, fragrances, and advanced materials.
• Analytical Standard: Provides a reference standard for chromatographic methods (HPLC, GC) to determine enantiomeric purity.
