Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chloro-N-(4-chlorophenyl)-N-(1,1-dioxido-2,3-dihydrothiophen-3-yl)benzamide.
4-Chloro-N-(4-chlorophenyl)-N-(1,1-dioxido-2,3-dihydrothiophen-3-yl)benzamide (CAS 303094-05-5) is a high-purity analytical reference standard with the molecular formula C17H13Cl2NO3S and a molecular weight of 382.26 g/mol.
The molecular framework of 4-Chloro-N-(4-chlorophenyl)-N-(1,1-dioxido-2,3-dihydrothiophen-3-yl)benzamide (C17H13Cl2NO3S) is characterized by a steroid 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chloro-N-(4-chlorophenyl)-N-(1,1-dioxido-2,3-dihydrothiophen-3-yl)benzamide 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.
