Chemical Structure
Description
2-[(4-Chlorophenyl)sulfanyl]-N-[(4-methoxyphenyl)methyl]pyridine-3-carboxamide (CAS 866153-85-7), molecular formula C20H17ClN2O2S and molecular weight 384.88 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H17ClN2O2S, 2-[(4-Chlorophenyl)sulfanyl]-N-[(4-methoxyphenyl)methyl]pyridine-3-carboxamide contains a steroid core, 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 384.88 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.
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.
As a certified reference material (CRM), 2-[(4-Chlorophenyl)sulfanyl]-N-[(4-methoxyphenyl)methyl]pyridine-3-carboxamide 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.
