Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 215.11 g/mol gives 1-Bromo-3-(ethanesulfonyl)propane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-3-(ethanesulfonyl)propane (CAS 98137-26-9) is a high-purity analytical reference standard with the molecular formula C5H11BrO2S and a molecular weight of 215.11 g/mol.
The molecular framework of 1-Bromo-3-(ethanesulfonyl)propane (C5H11BrO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-(ethanesulfonyl)propane 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.
