Description
(R)-3-[4-[2-(4-Fluorophenyl)-5,5-dimethyl-1,3-dioxan-2-yl]-1-oxobutyl]-4-phenyl-2-oxazolidinone (CAS 1478664-06-0) is a high-purity analytical reference standard with the molecular formula C25H28FNO5 and a molecular weight of 441.49 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (R)-3-[4-[2-(4-Fluorophenyl)-5,5-dimethyl-1,3-dioxan-2-yl]-1-oxobutyl]-4-phenyl-2-oxazolidinone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 441.49 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).
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), (R)-3-[4-[2-(4-Fluorophenyl)-5,5-dimethyl-1,3-dioxan-2-yl]-1-oxobutyl]-4-phenyl-2-oxazolidinone 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.
