7-(3-Bromophenyl)-2-(methylthio)thieno[3,2-d]pyrimidin-4(3H)-one CAS 1325303-76-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(3-Bromophenyl)-2-(methylthio)thieno[3,2-d]pyrimidin-4(3H)-one.

7-(3-Bromophenyl)-2-(methylthio)thieno[3,2-d]pyrimidin-4(3H)-one (CAS 1325303-76-1), molecular formula C13H9BrN2OS2 and molecular weight 353.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7-(3-Bromophenyl)-2-(methylthio)thieno[3,2-d]pyrimidin-4(3H)-one (C13H9BrN2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 353.26 g/mol, it falls into the moderately-high-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), 7-(3-Bromophenyl)-2-(methylthio)thieno[3,2-d]pyrimidin-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.
