Description

Ammonium (1S-Endo)-[3-Bromo-7,7-Dimethyl-2-Oxobicyclo[2.2.1]Hept-1-Yl]Methanesulphonate is a high-purity, specialized organic salt featuring a complex, functionalized norbornane (bicyclo[2.2.1]heptane) core structure. This compound is valued as a critical advanced pharmaceutical intermediate (API intermediate) and a versatile chiral building block for asymmetric synthesis. It is essential for research and production in fine chemical, agrochemical, and pharmaceutical sectors, where its unique stereochemistry and reactive sites enable the construction of complex molecules.

Application

• Pharmaceutical Intermediate: Key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) agents and other therapeutic compounds.
• Asymmetric Synthesis: Serves as a sophisticated chiral building block or auxiliary in stereoselective organic reactions to create enantiomerically pure products.
• Agrochemical Research: Used in the development of novel pesticides and herbicides, leveraging its brominated and functionalized norbornane scaffold.
• Material Science: Potential monomer or additive for creating specialized polymers with unique thermal or mechanical properties.
• Catalyst Ligand Synthesis: Intermediate for the preparation of complex ligands used in transition metal catalysis.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic chemistry and medicinal chemistry programs.

Quality Control

Our production of Ammonium (1S-Endo)-[3-Bromo-7,7-Dimethyl-2-Oxobicyclo[2.2.1]Hept-1-Yl]Methanesulphonate adheres to stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral purity, NMR for structural confirmation, and KF titration for moisture content. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to ensure traceability, consistency, and compliance with your research or cGMP manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which may affect stability and handling properties. Keep away from incompatible materials.
