3,3-Dioctyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine CAS 259139-23-6

Description

The occurrence of 3,3-Dioctyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,3-Dioctyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine (CAS 259139-23-6) is a high-purity analytical reference standard with the molecular formula C23H40O2S and a molecular weight of 380.63 g/mol.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 3,3-Dioctyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
