Chemical Structure
Description
The molecular framework of 4-((Chloromethyl)sulfonyl)-2-methyl-1,4-oxazepane (C7H14ClNO3S) is characterized by an amide group, a sulfone group, a carboxylic acid 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.
4-((Chloromethyl)sulfonyl)-2-methyl-1,4-oxazepane (CAS 1341747-88-3) is a high-purity analytical reference standard with the molecular formula C7H14ClNO3S and a molecular weight of 227.71 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
