Description
CATO supplies 2-(3,4-Dibromo-2-oxo-2,5-dihydro-1H-pyrrol-1-yl)acetonitrile (CAS 1706451-45-7), a certified reference material (molecular formula C6H4Br2N2O, MW 279.92 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-(3,4-Dibromo-2-oxo-2,5-dihydro-1H-pyrrol-1-yl)acetonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.92 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).
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-(3,4-Dibromo-2-oxo-2,5-dihydro-1H-pyrrol-1-yl)acetonitrile 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.
