Chemical Structure

Tetrahydrothiophene-2,2,5,5-d4 CAS 31081-24-0 chemical structure

Description

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.

Tetrahydrothiophene-2,2,5,5-d4 (CAS 31081-24-0), molecular formula C4H4D4S and molecular weight 92.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Tetrahydrothiophene-2,2,5,5-d4 (C4H4D4S) contains deuterium isotope labeling, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 92.20 g/mol, it falls into the low-molecular-weight range. 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.
