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 3-(7-Chloro-4-oxo-2-sulfanyl-3,4-dihydroquinazolin-3-yl)propanoic acid (CAS 852940-56-8), a certified reference material (molecular formula C11H9ClN2O3S, MW 284.72 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(7-Chloro-4-oxo-2-sulfanyl-3,4-dihydroquinazolin-3-yl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.72 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), 3-(7-Chloro-4-oxo-2-sulfanyl-3,4-dihydroquinazolin-3-yl)propanoic acid 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.
