Description

(1R,2R)-(+)-1,2-Diaminocyclohexane L-Tartrate is a high-purity chiral diamine salt, widely recognized as a versatile and effective chiral ligand and resolving agent in asymmetric synthesis. Its primary commercial value lies in its ability to induce high enantioselectivity in catalytic hydrogenation and other key transformations, directly impacting the efficiency and cost of producing single-enantiomer pharmaceuticals and fine chemicals. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality chiral auxiliaries to develop novel active ingredients and specialty compounds.

Application

• Asymmetric Catalysis: Serves as a privileged chiral ligand for transition metal catalysts (e.g., Ru, Rh) in enantioselective hydrogenation reactions.
• Pharmaceutical Intermediate Synthesis: Critical for the resolution of racemic mixtures and the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs).
• Chiral Resolution Agent: Used to separate enantiomers of carboxylic acids and other acidic compounds via diastereomeric salt formation.
• Agrochemical Production: Employed in the synthesis of chiral herbicides, fungicides, and pesticides to enhance biological activity and reduce environmental impact.
• Material Science: Acts as a building block or chiral modifier in the development of advanced polymers and liquid crystals.
• Academic & Industrial R&D: A fundamental tool for method development and discovery chemistry in asymmetric synthesis.
