Chemical Structure

4-Bromobutan-2-one CAS 28509-46-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 151.00 g/mol gives 4-Bromobutan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Bromobutan-2-one (CAS 28509-46-8), a certified reference material (molecular formula C4H7BrO, MW 151.00 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, bromine substitution, 4-Bromobutan-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.00 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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