Chemical Structure

4-bromooxan-3-one CAS 1378680-33-1 chemical structure

Description

CATO supplies 4-bromooxan-3-one (CAS 1378680-33-1), a certified reference material (molecular formula C5H7BrO2, MW 179.01 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 4-bromooxan-3-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 179.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4-bromooxan-3-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.
