Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 199.27 g/mol gives N,N-dimethyl-4-(methylsulfonyl)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N,N-dimethyl-4-(methylsulfonyl)aniline (CAS 33599-22-3), molecular formula C9H13NO2S and molecular weight 199.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N,N-dimethyl-4-(methylsulfonyl)aniline (C9H13NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures N,N-dimethyl-4-(methylsulfonyl)aniline 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.
