Chemical Structure
Description
2-bromo-1-(3-chloropyridin-4-yl)ethan-1-one hydrobromide (CAS 1187669-52-8), molecular formula C7H5BrClNOHBr and molecular weight 315.39 g/mol, is a CATO reference standard with documented purity and traceability.
2-bromo-1-(3-chloropyridin-4-yl)ethan-1-one hydrobromide (C7H5BrClNOHBr) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-bromo-1-(3-chloropyridin-4-yl)ethan-1-one hydrobromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
