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 (3S)-3-methyloxolane-2,5-dione.
(3S)-3-methyloxolane-2,5-dione (CAS 6973-20-2) is a high-purity analytical reference standard with the molecular formula C5H6O3 and a molecular weight of 114.10 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (3S)-3-methyloxolane-2,5-dione is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.10 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.
