Description
CATO manufactures N-(2-Chlorophenyl)-1,3-propanesultam under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
N-(2-Chlorophenyl)-1,3-propanesultam (CAS 71703-11-2) is a high-purity analytical reference standard with the molecular formula C9H10ClNO2S and a molecular weight of 231.70 g/mol.
The molecular framework of N-(2-Chlorophenyl)-1,3-propanesultam (C9H10ClNO2S) 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.
