2-(((3,5-Dimethylisoxazol-4-yl)methyl)thio)-3-phenyl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-one CAS 314260-92-9

Description

2-(((3,5-Dimethylisoxazol-4-yl)methyl)thio)-3-phenyl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-one (CAS 314260-92-9), molecular formula C22H21N3O2S2 and molecular weight 423.55 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(((3,5-Dimethylisoxazol-4-yl)methyl)thio)-3-phenyl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 423.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-(((3,5-Dimethylisoxazol-4-yl)methyl)thio)-3-phenyl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-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.
