4-ethyl-2,3-dihydro-1,3-thiazole-2-thione CAS 33120-75-1

Description

Compared with other compounds in its class, the molecular weight of 145.25 g/mol gives 4-ethyl-2,3-dihydro-1,3-thiazole-2-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-ethyl-2,3-dihydro-1,3-thiazole-2-thione (CAS 33120-75-1), molecular formula C5H7NS2 and molecular weight 145.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, 4-ethyl-2,3-dihydro-1,3-thiazole-2-thione is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.25 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.
