Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 1-(4-Chlorobenzyl)-4,6-dimethyl-3-(phenylsulfonyl)pyridin-2(1H)-one (CAS 306977-16-2), a certified reference material (molecular formula C20H18ClNO3S, MW 387.88 g/mol) for analytical method development and quality control.
Structurally, 1-(4-Chlorobenzyl)-4,6-dimethyl-3-(phenylsulfonyl)pyridin-2(1H)-one (C20H18ClNO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 387.88 g/mol, it falls into the moderately-high-molecular-weight range. 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.
