As a certified reference material (CRM), 2-Bromoethanesulfonic 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.
CATO supplies 2-Bromoethanesulfonic Acid (CAS 26978-65-4), a certified reference material (molecular formula C2H5BrO3S, MW 189.03 g/mol) for analytical method development and quality control.
Based on its molecular formula C2H5BrO3S, 2-Bromoethanesulfonic Acid contains a sulfone group, a carboxylic acid group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 189.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
