Description

Ammonium (-)-3-Bromo-8-Camphorsulfonate is a high-purity chiral ammonium salt derived from camphorsulfonic acid, serving as a critical intermediate and resolving agent in asymmetric synthesis. Its value lies in providing a reliable source of a non-racemic counterion for the purification and crystallization of enantiomerically pure compounds, particularly pharmaceutical actives. This product is essential for research laboratories and production facilities in the pharmaceutical, agrochemical, and fine chemical sectors that require stringent control over stereochemistry.

Application

• Chiral Resolution Agent: Used for the separation of enantiomers via diastereomeric salt formation in pharmaceutical intermediate synthesis.
• Asymmetric Synthesis Catalyst/Additive: Acts as a chiral inducer or phase-transfer catalyst in stereoselective reactions.
• Pharmaceutical Intermediate: A key building block in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs).
• Reference Standard: Serves as an analytical standard for quality control and method development in chiral HPLC analysis.
• Fine Chemical Synthesis: Employed in the preparation of specialty chemicals, flavors, and fragrances where optical purity is paramount.
• Academic & Industrial R&D: A valuable reagent for method development and process chemistry research in asymmetric catalysis.

Quality Control

Our Ammonium (-)-3-Bromo-8-Camphorsulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure compliance with stringent specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

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