Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.97 g/mol gives 1-Bromo-3-hydroxypropan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-3-hydroxypropan-2-one (CAS 38987-72-3), molecular formula C3H5BrO2 and molecular weight 152.97 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-3-hydroxypropan-2-one (C3H5BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1-Bromo-3-hydroxypropan-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.
