Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(2-Chlorophenyl)thiomorpholine-3,5-dione (CAS 338421-18-4) is a high-purity analytical reference standard with the molecular formula C10H8ClNO2S and a molecular weight of 241.69 g/mol.
The molecular framework of 4-(2-Chlorophenyl)thiomorpholine-3,5-dione (C10H8ClNO2S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4-(2-Chlorophenyl)thiomorpholine-3,5-dione 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.
