Description

3-Cyclohexene-1-Carbonylbromide(9Ci) is a versatile and reactive organic bromide intermediate, essential for advanced synthetic chemistry. Its value lies in its ability to introduce the carbonyl bromide functional group into complex molecular frameworks, enabling the construction of pharmaceuticals, agrochemicals, and specialty materials. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for building novel compounds and scaling up synthetic routes.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for candidates with cyclic or constrained structures.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific cyclic motifs.
• Fine Chemical Production: Serves as a precursor for creating complex ligands, catalysts, and specialty polymers used in material science.
• Academic & Industrial R&D: A valuable reagent for method development and exploring new carbon-carbon and carbon-heteroatom bond-forming reactions in organic chemistry laboratories.
• Peptide Mimetic Chemistry: Employed in the design and synthesis of peptide analogs and other bio-active molecules where the cyclohexene scaffold is incorporated.

Quality Control

Our 3-Cyclohexene-1-Carbonylbromide(9Ci) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography and spectroscopic methods, to verify identity and purity. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory documentation needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and incompatible materials.
