2-(Benzylthio)-4-(phenylthio)benzo[4,5]thieno[3,2-d]pyrimidine CAS 478030-00-1

Description

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.

2-(Benzylthio)-4-(phenylthio)benzo[4,5]thieno[3,2-d]pyrimidine (CAS 478030-00-1), molecular formula C23H16N2S3 and molecular weight 416.58 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Benzylthio)-4-(phenylthio)benzo[4,5]thieno[3,2-d]pyrimidine (C23H16N2S3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
