Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-bromo-4,5-dihydro-3H-oxepino[2,3-b]pyridin-2-one.
CATO supplies 7-bromo-4,5-dihydro-3H-oxepino[2,3-b]pyridin-2-one (CAS 2387601-00-3), a certified reference material (molecular formula C9H14BrNO2, MW 248.12 g/mol) for analytical method development and quality control.
7-bromo-4,5-dihydro-3H-oxepino[2,3-b]pyridin-2-one (C9H14BrNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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 7-bromo-4,5-dihydro-3H-oxepino[2,3-b]pyridin-2-one 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.
