Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Mercapto-3-propyl-3H-quinazolin-4-one.
2-Mercapto-3-propyl-3H-quinazolin-4-one (CAS 63586-34-5) is a high-purity analytical reference standard with the molecular formula C11H12N2OS and a molecular weight of 220.29 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-Mercapto-3-propyl-3H-quinazolin-4-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-Mercapto-3-propyl-3H-quinazolin-4-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.
