Description

Isopropyl (1S)-(+)-10-Camphorsulfate is a high-purity chiral sulfonate ester derivative of camphor, a naturally occurring terpenoid. This compound serves as a valuable chiral auxiliary, resolving agent, and synthetic intermediate in the production of enantiomerically pure pharmaceuticals and fine chemicals. It is essential for research and manufacturing organizations in the pharmaceutical, agrochemical, and advanced materials sectors that require precise stereochemical control. The product is supplied to meet the stringent quality demands of modern asymmetric synthesis.

Application

• As a chiral resolving agent for the separation of racemic mixtures of amines, acids, and alcohols.
• Utilized as a key chiral auxiliary in asymmetric synthesis to induce stereoselectivity in carbon-carbon bond-forming reactions.
• An important intermediate in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs) and agrochemicals.
• Employed in catalyst ligand development for homogeneous catalysis.
• Used in analytical chemistry as a reference standard for chiral chromatography (HPLC, GC).
• Applied in academic and industrial R&D for exploring new methodologies in stereoselective synthesis.
