Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-(4-Chlorophenyl)-4h,5h,6h,7h-thieno[3,2-c]pyridine (CAS 213462-12-5), a certified reference material (molecular formula C13H12ClNS, MW 249.76 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H12ClNS, 4-(4-Chlorophenyl)-4h,5h,6h,7h-thieno[3,2-c]pyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.76 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.
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.
