Chemical Structure
Description
CATO supplies 2,4-dichloro-7-(trifluoromethyl)thieno[3,2-d]pyrimidine (CAS 1442083-00-2), a certified reference material (molecular formula C7H9Cl2F3N2S, MW 281.13 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H9Cl2F3N2S, 2,4-dichloro-7-(trifluoromethyl)thieno[3,2-d]pyrimidine contains a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 281.13 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.
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.
