Chemical Structure
Description
As a certified reference material (CRM), (3R,4R,5R)-5-(benzyloxymethyl)-3-fluoro-4-hydroxy-3-methyl-tetrahydrofuran-2-one 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.
(3R,4R,5R)-5-(benzyloxymethyl)-3-fluoro-4-hydroxy-3-methyl-tetrahydrofuran-2-one (CAS 1583260-49-4), molecular formula C13H21FO4 and molecular weight 260.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (3R,4R,5R)-5-(benzyloxymethyl)-3-fluoro-4-hydroxy-3-methyl-tetrahydrofuran-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
