Description

Tributyl(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)stannane (CAS 175922-79-9), molecular formula C18H32O2SSn and molecular weight 431.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Tributyl(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)stannane (C18H32O2SSn) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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 431.22 g/mol, it falls into the moderately-high-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.

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.
