Compared with other compounds in its class, the molecular weight of 151.00 g/mol gives 3-Bromobutan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Bromobutan-2-one (CAS 814-75-5), a certified reference material (molecular formula C4H7BrO, MW 151.00 g/mol) for analytical method development and quality control.
Structurally, 3-Bromobutan-2-one (C4H7BrO) contains a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 151.00 g/mol, it falls into the medium-molecular-weight range. 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), 3-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.
