3-(2,5-Dimethylphenyl)-2-mercapto-6-phenylthieno[3,2-d]pyrimidin-4(3h)-one CAS 522606-38-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2,5-Dimethylphenyl)-2-mercapto-6-phenylthieno[3,2-d]pyrimidin-4(3h)-one.

3-(2,5-Dimethylphenyl)-2-mercapto-6-phenylthieno[3,2-d]pyrimidin-4(3h)-one (CAS 522606-38-8), molecular formula C20H16N2OS2 and molecular weight 364.48 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H16N2OS2, 3-(2,5-Dimethylphenyl)-2-mercapto-6-phenylthieno[3,2-d]pyrimidin-4(3h)-one contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 364.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-(2,5-Dimethylphenyl)-2-mercapto-6-phenylthieno[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.
