Chemical Structure
Description
CATO supplies tert-butyl 8-chloro-3,5-dihydro-2H-pyrido[3,2-f][1,4]oxazepine-4-carboxylate (CAS 956434-30-3), a certified reference material (molecular formula C13H17ClN2O3, MW 284.74 g/mol) for analytical method development and quality control.
tert-butyl 8-chloro-3,5-dihydro-2H-pyrido[3,2-f][1,4]oxazepine-4-carboxylate (C13H17ClN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures tert-butyl 8-chloro-3,5-dihydro-2H-pyrido[3,2-f][1,4]oxazepine-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.
