Chemical Structure
Description
2-Bromo-5-cyclopropylbenzoyl chloride (CAS 2168631-98-7), molecular formula C10H8BrClO and molecular weight 259.53 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-5-cyclopropylbenzoyl chloride (C10H8BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-Bromo-5-cyclopropylbenzoyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
