Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3R,4R,5S)-5-((Benzoyloxy)methyl)-4-methyltetrahydrofuran-2,3-diyl diacetate (CAS 444019-07-2), molecular formula C17H20O7 and molecular weight 336.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (3R,4R,5S)-5-((Benzoyloxy)methyl)-4-methyltetrahydrofuran-2,3-diyl diacetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (3R,4R,5S)-5-((Benzoyloxy)methyl)-4-methyltetrahydrofuran-2,3-diyl diacetate 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.
