Chemical Structure

Tetrahydrofuran-d8 CAS 1693-74-9 chemical structure

Description

CATO supplies Tetrahydrofuran-d8 (CAS 1693-74-9), a certified reference material (molecular formula C4D8O, MW 80.16 g/mol) for analytical method development and quality control.

Structurally, Tetrahydrofuran-d8 (C4D8O) contains deuterium isotope labeling, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 80.16 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.

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.
