Sitstanol-5,6,22,23-d<SUB>4</SUB> CAS 150044-25-0

Description

The occurrence of Sitstanol-5,6,22,23-d<SUB>4</SUB> is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Sitstanol-5,6,22,23-d<SUB>4</SUB> (CAS 150044-25-0), a certified reference material (molecular formula C29H48D4O, MW 420.75 g/mol) for analytical method development and quality control.

Structurally, Sitstanol-5,6,22,23-d<SUB>4</SUB> (C29H48D4O) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 420.75 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.
