Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Bromo-1-(4,5-dichlorothiophen-2-yl)ethan-1-one (CAS 63723-02-4), a certified reference material (molecular formula C6H3BrCl2OS, MW 273.96 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 2-Bromo-1-(4,5-dichlorothiophen-2-yl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-Bromo-1-(4,5-dichlorothiophen-2-yl)ethan-1-one 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.
