Chemical Structure

(2R,3R)-3-Hydroxy-2-(hydroxymethyl)-2,3-dihydro-4H-pyran-4-one CAS 14125-64-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3R)-3-Hydroxy-2-(hydroxymethyl)-2,3-dihydro-4H-pyran-4-one.

(2R,3R)-3-Hydroxy-2-(hydroxymethyl)-2,3-dihydro-4H-pyran-4-one (CAS 14125-64-5) is a high-purity analytical reference standard with the molecular formula C6H8O4 and a molecular weight of 144.13 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (2R,3R)-3-Hydroxy-2-(hydroxymethyl)-2,3-dihydro-4H-pyran-4-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.13 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
