(2R,3S,4R)-2-(Hydroxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate CAS 82295-98-5

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,3S,4R)-2-(Hydroxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.21 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).

(2R,3S,4R)-2-(Hydroxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate (CAS 82295-98-5), molecular formula C10H14O6 and molecular weight 230.21 g/mol, is a CATO reference standard with documented purity and traceability.

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), (2R,3S,4R)-2-(Hydroxymethyl)-3,4-dihydro-2H-pyran-3,4-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.
