Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-Methyl-N'-(2-oxo-1-phenyl-2-(piperidin-1-yl)ethylidene)benzenesulfonohydrazide.
(E)-4-Methyl-N'-(2-oxo-1-phenyl-2-(piperidin-1-yl)ethylidene)benzenesulfonohydrazide (CAS 219915-67-0), molecular formula C20H23N3O3S and molecular weight 385.48 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (E)-4-Methyl-N'-(2-oxo-1-phenyl-2-(piperidin-1-yl)ethylidene)benzenesulfonohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 385.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (E)-4-Methyl-N'-(2-oxo-1-phenyl-2-(piperidin-1-yl)ethylidene)benzenesulfonohydrazide 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.
