Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,4-dichlorophenyl)methyl N-[1-(4-chlorobenzenesulfonyl)piperidin-4-yl]carbamate 478047-72-2 4R-1161.
(2,4-dichlorophenyl)methyl N-[1-(4-chlorobenzenesulfonyl)piperidin-4-yl]carbamate 478047-72-2 4R-1161 (CAS 478047-72-2), molecular formula C19H19Cl3N2O4S and molecular weight 477.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,4-dichlorophenyl)methyl N-[1-(4-chlorobenzenesulfonyl)piperidin-4-yl]carbamate 478047-72-2 4R-1161 (C19H19Cl3N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (2,4-dichlorophenyl)methyl N-[1-(4-chlorobenzenesulfonyl)piperidin-4-yl]carbamate 478047-72-2 4R-1161 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.
