Description

(S)-(-)-2-Amino-3-Methyl-1,1-Diphenyl-1-Butanol is a high-purity chiral amino alcohol building block of significant importance in asymmetric synthesis. Its value lies in its utility as a versatile ligand and resolving agent for the production of enantiomerically pure pharmaceuticals and fine chemicals. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and advanced material sectors for developing chiral active pharmaceutical ingredients (APIs) and catalysts.

Application

• As a chiral ligand or catalyst in asymmetric hydrogenation and carbon-carbon bond-forming reactions.
• As a resolving agent for the separation of racemic mixtures of carboxylic acids and other chiral compounds.
• As a key synthetic intermediate in the research and development of novel pharmaceutical candidates.
• In the preparation of chiral auxiliaries for use in stereoselective organic synthesis.
• For the synthesis of complex natural products and specialty chemicals requiring high enantiomeric purity.
• In methodological studies and process chemistry within academic and industrial R&D laboratories.
