Chemical Structure
Description
The occurrence of (3-(Tert-butyl)-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)(2-chlorophenyl)methanone is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (3-(Tert-butyl)-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)(2-chlorophenyl)methanone (CAS 478043-17-3), a certified reference material (molecular formula C19H20ClNO2, MW 329.82 g/mol) for analytical method development and quality control.
The molecular framework of (3-(Tert-butyl)-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)(2-chlorophenyl)methanone (C19H20ClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
CATO manufactures (3-(Tert-butyl)-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)(2-chlorophenyl)methanone 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.
