Description

Methyl (1S)-(+)-10-Camphorsulfonate is a high-purity, chiral sulfonate derivative of camphor, serving as a critical chiral auxiliary and resolving agent in asymmetric synthesis. Its primary value lies in its ability to induce chirality and separate enantiomers, which is fundamental for producing optically pure pharmaceutical intermediates and fine chemicals. This compound is essential for research and production laboratories in the pharmaceutical, agrochemical, and advanced material sectors that require precise stereochemical control.

Application

• As a chiral resolving agent for the separation of racemic mixtures of amines, acids, and alcohols.
• Employed as a key chiral auxiliary in asymmetric synthesis to control stereochemistry in carbon-carbon bond-forming reactions.
• Used in the synthesis of optically active pharmaceutical intermediates, particularly for central nervous system (CNS) agents and antiviral drugs.
• As a precursor or catalyst modifier in the development of specialty catalysts for enantioselective transformations.
• In analytical chemistry as a derivatizing agent for chiral chromatography to determine enantiomeric purity.
• For research and development of novel agrochemicals where specific stereoisomers exhibit desired biological activity.
• In the preparation of ionic liquids and chiral selectors for separation membranes.
