2-Ethyl-4-(4-methylthiazol-2-yl)thieno[3,2-d]pyrimidine CAS 443148-31-0

Description

Based on its molecular formula C12H11N3S2, 2-Ethyl-4-(4-methylthiazol-2-yl)thieno[3,2-d]pyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.37 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.

CATO supplies 2-Ethyl-4-(4-methylthiazol-2-yl)thieno[3,2-d]pyrimidine (CAS 443148-31-0), a certified reference material (molecular formula C12H11N3S2, MW 261.37 g/mol) for analytical method development and quality control.

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.
