Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
9-((3-Chloro-4-methylphenyl)sulfonyl)-1,5-dioxa-9-azaspiro[5.5]undecane (CAS 1022389-35-0) is a high-purity analytical reference standard with the molecular formula C15H20ClNO4S and a molecular weight of 345.84 g/mol.
The molecular framework of 9-((3-Chloro-4-methylphenyl)sulfonyl)-1,5-dioxa-9-azaspiro[5.5]undecane (C15H20ClNO4S) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
