Description

(1R,2R)-(+)-1,2-Cyclohexanediamine L-Tartrate CAS NO 32044-22-7 is a high-purity chiral diamine salt, specifically the L-tartrate salt of the (1R,2R) enantiomer of 1,2-diaminocyclohexane. This compound is a critical chiral building block and ligand in asymmetric synthesis, enabling the production of enantiomerically pure pharmaceuticals and fine chemicals. It is essential for researchers and manufacturers in pharmaceutical development, agrochemical synthesis, and advanced material science who require a reliable source of high-stereochemical purity.

Application

• Asymmetric Catalysis: Serves as a key precursor for chiral ligands and catalysts used in hydrogenation, epoxidation, and other enantioselective transformations.
• Pharmaceutical Intermediates: A vital chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting the central nervous system and anti-infectives.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Chiral Resolution Agent: Employed for the separation of racemic mixtures of carboxylic acids and other acidic compounds.
• Coordination Chemistry: Acts as a chelating ligand for transition metals, forming complexes with applications in materials science and catalysis.
• Research & Development: A standard reagent in academic and industrial R&D for developing new asymmetric methodologies.
