Chemical Structure

2-chlorothieno[2,3-d]pyrimidine CAS 83259-30-7 chemical structure

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.

CATO supplies 2-chlorothieno[2,3-d]pyrimidine (CAS 83259-30-7), a certified reference material (molecular formula C6H11ClN2S, MW 178.68 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H11ClN2S, 2-chlorothieno[2,3-d]pyrimidine contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 178.68 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.

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.
