Methyl 2-(Chloromethyl)-4-hydroxy-5-methylthieno[2,3-d]pyrimidine-6-carboxylate CAS 565166-96-3

Description

Based on its molecular formula C10H9ClN2O3S, Methyl 2-(Chloromethyl)-4-hydroxy-5-methylthieno[2,3-d]pyrimidine-6-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies Methyl 2-(Chloromethyl)-4-hydroxy-5-methylthieno[2,3-d]pyrimidine-6-carboxylate (CAS 565166-96-3), a certified reference material (molecular formula C10H9ClN2O3S, MW 272.71 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.
