Chemical Structure
Description
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.
CATO supplies Tert-butyl 6-hydroxy-6-(trifluoromethyl)-1,4-oxazepane-4-carboxylate (CAS 1823776-46-0), a certified reference material (molecular formula C11H18F3NO4, MW 285.26 g/mol) for analytical method development and quality control.
The molecular framework of Tert-butyl 6-hydroxy-6-(trifluoromethyl)-1,4-oxazepane-4-carboxylate (C11H18F3NO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
CATO manufactures Tert-butyl 6-hydroxy-6-(trifluoromethyl)-1,4-oxazepane-4-carboxylate 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.
