Chemical Structure
Description
[(2R,3R)-2-(benzyloxymethyl)-4,4-difluoro-5-oxo-tetrahydrofuran-3-yl] benzoate (CAS 1583260-41-6) is a high-purity analytical reference standard with the molecular formula C19H28F2O5 and a molecular weight of 374.42 g/mol.
[(2R,3R)-2-(benzyloxymethyl)-4,4-difluoro-5-oxo-tetrahydrofuran-3-yl] benzoate (C19H28F2O5) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), [(2R,3R)-2-(benzyloxymethyl)-4,4-difluoro-5-oxo-tetrahydrofuran-3-yl] benzoate 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.
