Chemical Structure
Description
The occurrence of (S)-2-(5-Oxotetrahydrofuran-2-yl)acetic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-2-(5-Oxotetrahydrofuran-2-yl)acetic acid (CAS 66512-67-2), molecular formula C6H8O4 and molecular weight 144.13 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-2-(5-Oxotetrahydrofuran-2-yl)acetic acid (C6H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
