Description

(2S,3S)-(-)-2,3-Butanediamine Dihydrochloride is a high-purity chiral diamine salt, serving as a critical building block in asymmetric synthesis. Its defined stereochemistry makes it an invaluable ligand and chiral auxiliary for producing enantiomerically pure pharmaceuticals and fine chemicals. This compound is essential for research and production in pharmaceutical development, agrochemical synthesis, and advanced material science, where precise stereocontrol is paramount.

Application

• Pharmaceutical Intermediate: Key chiral precursor for the synthesis of active pharmaceutical ingredients (APIs), particularly in antiviral and anticancer drug candidates.
• Asymmetric Catalyst Ligand: Used to construct chiral ligands for transition metal catalysts in enantioselective hydrogenation and carbon-carbon bond formation reactions.
• Chiral Resolution Agent: Employed in the separation of racemic mixtures of carboxylic acids and other compounds via diastereomeric salt formation.
• Agrochemical Synthesis: Building block for creating enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Complexing Agent: Used in analytical chemistry and metal ion sequestration due to its chelating properties.
• Polymer Modification: Serves as a monomer or cross-linking agent for producing specialty polymers with tailored properties.
