Chemical Structure
Description
As a certified reference material (CRM), 5-Bromofuran-2-sulfonyl fluoride 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 5-Bromofuran-2-sulfonyl fluoride (CAS 2137682-74-5), a certified reference material (molecular formula C4H2BrFO3S, MW 229.02 g/mol) for analytical method development and quality control.
Structurally, 5-Bromofuran-2-sulfonyl fluoride (C4H2BrFO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 229.02 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.
