3-(2-Chlorobenzyl)-2-mercapto-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid CAS 361150-31-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Chlorobenzyl)-2-mercapto-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid.

3-(2-Chlorobenzyl)-2-mercapto-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid (CAS 361150-31-4), molecular formula C16H11ClN2O3S and molecular weight 346.79 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(2-Chlorobenzyl)-2-mercapto-4-oxo-3,4-dihydroquinazoline-7-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.79 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.

As a certified reference material (CRM), 3-(2-Chlorobenzyl)-2-mercapto-4-oxo-3,4-dihydroquinazoline-7-carboxylic 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.
