2-bromocyclobutan-1-one CAS 1192-01-4

Description

Compared with other compounds in its class, the molecular weight of 148.99 g/mol gives 2-bromocyclobutan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-bromocyclobutan-1-one (CAS 1192-01-4) is a high-purity analytical reference standard with the molecular formula C4H5BrO and a molecular weight of 148.99 g/mol.

Owing to a hydroxyl group, an ether linkage, bromine substitution, 2-bromocyclobutan-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.99 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), 2-bromocyclobutan-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.
