Description

1,2-Dibromocyclohexane CAS NO 5401-62-7 is a versatile brominated cycloalkane compound primarily used as a key synthetic intermediate in organic chemistry. Its value lies in its ability to act as a robust alkylating agent and a precursor for constructing complex molecular frameworks. This chemical is essential for research and development laboratories, pharmaceutical synthesis, and specialty chemical manufacturing where precise bromination and ring functionalization are required.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of pesticides, herbicides, and other crop protection agents requiring brominated cyclic structures.
• Organic Synthesis & Research: Acts as a versatile reagent for cyclization reactions, ring-opening polymerizations, and the preparation of other functionalized cyclohexane derivatives.
• Liquid Crystal & Polymer Chemistry: Employed as a monomer or intermediate in the development of specialty polymers and liquid crystal materials.
• Cross-Coupling Reactions: Functions as a substrate in various metal-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) to form carbon-carbon bonds.
• Flame Retardant Additive Precursor: Can be utilized in the development of brominated flame retardants for materials science applications.

Quality Control

Our 1,2-Dibromocyclohexane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including purity by GC/HPLC, identity confirmation by FT-IR and NMR, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications is available for every batch upon request, supporting compliance with research and industrial application standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and metals. Due to its nature as a strong acid/organic solvent and highly volatile compound, containers must be kept tightly sealed and upright to minimize evaporation and moisture ingress. Recommended storage temperature is 2-8°C for long-term stability.
