Description

Benzenepropanoyl Chloride, 2-Bromo- is a specialized organic intermediate featuring both a reactive acid chloride group and a bromine substituent on the aromatic ring. This bifunctional nature makes it a valuable building block for the synthesis of complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists in the fine chemical and life science industries for constructing novel compounds and active ingredients.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), especially those requiring a benzoyl moiety with specific halogen substitution patterns.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the bromine atom allows for further functionalization.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Material Science Research: Employed in the synthesis of monomers for specialty polymers and advanced organic electronic materials.
• Chemical Biology Probes: Useful for the derivatization of biomolecules or the creation of fluorescent tags and other diagnostic tools.
• Custom Synthesis and Contract Manufacturing: A critical reagent for custom synthesis houses serving the pharmaceutical and biotechnology sectors.

Quality Control

Our Benzenepropanoyl Chloride, 2-Bromo- is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
