Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3-Chlorophenyl)-1,1-dioxo-2,3-dihydrothiophen-3-amine.
N-(3-Chlorophenyl)-1,1-dioxo-2,3-dihydrothiophen-3-amine (CAS 321977-85-9), molecular formula C10H10ClNO2S and molecular weight 243.71 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(3-Chlorophenyl)-1,1-dioxo-2,3-dihydrothiophen-3-amine (C10H10ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 243.71 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), N-(3-Chlorophenyl)-1,1-dioxo-2,3-dihydrothiophen-3-amine 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.
