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 3-((4-Chlorophenyl)sulfonyl)oxazolidin-2-one.
3-((4-Chlorophenyl)sulfonyl)oxazolidin-2-one (CAS 74668-35-2), molecular formula C9H8ClNO4S and molecular weight 261.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((4-Chlorophenyl)sulfonyl)oxazolidin-2-one (C9H8ClNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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), 3-((4-Chlorophenyl)sulfonyl)oxazolidin-2-one 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.
