3-Hydroxy-1-methylpyrrolidine-2,5-dione CAS 19948-27-7

Description

Compared with other compounds in its class, the molecular weight of 129.11 g/mol gives 3-Hydroxy-1-methylpyrrolidine-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Hydroxy-1-methylpyrrolidine-2,5-dione (CAS 19948-27-7) is a high-purity analytical reference standard with the molecular formula C5H7NO3 and a molecular weight of 129.11 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Hydroxy-1-methylpyrrolidine-2,5-dione is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.11 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.
