Description

Compared with other compounds in its class, the molecular weight of 253.32 g/mol gives 5-Amino-1-(2-methoxyethyl)-4-(4-methylthiazol-2-yl)-1,2-dihydro-3H-pyrrol-3-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Amino-1-(2-methoxyethyl)-4-(4-methylthiazol-2-yl)-1,2-dihydro-3H-pyrrol-3-one (CAS 951971-68-9), molecular formula C11H15N3O2S and molecular weight 253.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Amino-1-(2-methoxyethyl)-4-(4-methylthiazol-2-yl)-1,2-dihydro-3H-pyrrol-3-one (C11H15N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
