Chemical Structure
Description
CATO manufactures 3-(Tert-butyl)-4-tosyl-3,4-dihydro-2H-benzo[b][1,4]oxazine 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.
CATO supplies 3-(Tert-butyl)-4-tosyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 478043-16-2), a certified reference material (molecular formula C19H23NO3S, MW 345.46 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Tert-butyl)-4-tosyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (C19H23NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
