Chemical Structure
Description
(2S,3R,4S,5S)-5-(Methoxycarbonyl)tetrahydrofuran-2,3,4-triyl triacetate (CAS 68673-84-7), molecular formula C12H16O9 and molecular weight 304.25 g/mol, is a CATO reference standard with documented purity and traceability.
(2S,3R,4S,5S)-5-(Methoxycarbonyl)tetrahydrofuran-2,3,4-triyl triacetate (C12H16O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (2S,3R,4S,5S)-5-(Methoxycarbonyl)tetrahydrofuran-2,3,4-triyl triacetate 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.
