Chemical Structure

2-(Benzylthio)-4-(p-tolylthio)thieno[3,2-d]pyrimidine CAS 478067-45-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 380.55 g/mol gives 2-(Benzylthio)-4-(p-tolylthio)thieno[3,2-d]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(Benzylthio)-4-(p-tolylthio)thieno[3,2-d]pyrimidine (CAS 478067-45-7), a certified reference material (molecular formula C20H16N2S3, MW 380.55 g/mol) for analytical method development and quality control.

Structurally, 2-(Benzylthio)-4-(p-tolylthio)thieno[3,2-d]pyrimidine (C20H16N2S3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 380.55 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
