Chemical Structure

1,3-dibromobutan-2-one CAS 815-51-0 chemical structure

Description

As a certified reference material (CRM), 1,3-dibromobutan-2-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.

1,3-dibromobutan-2-one (CAS 815-51-0), molecular formula C4H6Br2O and molecular weight 229.90 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, bromine substitution, 1,3-dibromobutan-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.90 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.
