Chemical Structure

3-(2-Methoxyphenyl)quinazolin-4(3H)-one CAS 3977-52-4 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 3-(2-Methoxyphenyl)quinazolin-4(3H)-one.

3-(2-Methoxyphenyl)quinazolin-4(3H)-one (CAS 3977-52-4), molecular formula C15H12N2O2 and molecular weight 252.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(2-Methoxyphenyl)quinazolin-4(3H)-one (C15H12N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 252.27 g/mol, it falls into the medium-molecular-weight range. 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), 3-(2-Methoxyphenyl)quinazolin-4(3H)-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.
