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 4-phenyl-4H,5H,6H,7H-thieno[3,2-c]pyridine hydrochloride (CAS 95725-55-6), a certified reference material (molecular formula C13H13NSHCl, MW 251.77 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H13NSHCl, 4-phenyl-4H,5H,6H,7H-thieno[3,2-c]pyridine hydrochloride 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 251.77 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.
As a certified reference material (CRM), 4-phenyl-4H,5H,6H,7H-thieno[3,2-c]pyridine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
