Chemical Structure

9-Methyl-2-(propylthio)-5H-thiochromeno[4,3-d]pyrimidine CAS 478246-89-8 chemical structure

Description

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.

9-Methyl-2-(propylthio)-5H-thiochromeno[4,3-d]pyrimidine (CAS 478246-89-8) is a high-purity analytical reference standard with the molecular formula C15H16N2S2 and a molecular weight of 288.43 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 9-Methyl-2-(propylthio)-5H-thiochromeno[4,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.43 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.
