Chemical Structure
Description
As a certified reference material (CRM), 5-Methylfuran-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.
5-Methylfuran-2-sulfonyl fluoride (CAS 2138274-28-7) is a high-purity analytical reference standard with the molecular formula C5H5FO3S and a molecular weight of 164.15 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 5-Methylfuran-2-sulfonyl fluoride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
