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 2-Bromo-1-(1,4-oxazepan-4-yl)ethan-1-one (CAS 1339830-34-0), a certified reference material (molecular formula C7H12BrNO2, MW 222.08 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-1-(1,4-oxazepan-4-yl)ethan-1-one (C7H12BrNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.
As a certified reference material (CRM), 2-Bromo-1-(1,4-oxazepan-4-yl)ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
