Chemical Structure
Description
As a certified reference material (CRM), 1-(3-Bromophenyl)-2-chloroethanone 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.
CATO supplies 1-(3-Bromophenyl)-2-chloroethanone (CAS 21886-58-8), a certified reference material (molecular formula C8H6BrClO, MW 233.49 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 1-(3-Bromophenyl)-2-chloroethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
