Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 219.05 g/mol gives 2-Hydroxy-3-bromopropanesulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Hydroxy-3-bromopropanesulfonic acid (CAS CATO-C3D-262577) is a high-purity analytical reference standard with the molecular formula C3H7BrO4S and a molecular weight of 219.05 g/mol.
2-Hydroxy-3-bromopropanesulfonic acid (C3H7BrO4S) contains a sulfone group, a carboxylic acid group, an ether linkage, bromine substitution. It is notably hygroscopic, 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), 2-Hydroxy-3-bromopropanesulfonic acid 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.
