Description

L-10-Camphorsulfonic Acid Ammonium Salt is a high-purity chiral ammonium salt derived from camphorsulfonic acid, a key building block in asymmetric synthesis. This compound is valued for its role as a versatile resolving agent and chiral auxiliary, enabling the production of enantiomerically pure pharmaceuticals and fine chemicals. It is essential for research laboratories and industrial-scale manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors seeking reliable, high-quality chiral intermediates.

Application

• As a chiral resolving agent for the separation of racemic mixtures of amines, amino acids, and other basic compounds.
• Utilized as a chiral catalyst or additive in asymmetric synthesis to induce enantioselectivity.
• Key intermediate in the research and development of pharmaceutical active ingredients (APIs) requiring specific stereochemistry.
• Used in the synthesis of specialty fine chemicals and advanced materials where optical purity is critical.
• Application in analytical chemistry as a reference standard or for chiral chromatography.
• Potential use in agrochemical research for creating enantiomerically pure herbicides or pesticides.

Quality Control

Our L-10-Camphorsulfonic Acid Ammonium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific rotation is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
