Description

Compared with other compounds in its class, the molecular weight of 417.46 g/mol gives S-(8-(Ethoxy(4-nitrophenoxy)phosphoryl)octyl) ethanethioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies S-(8-(Ethoxy(4-nitrophenoxy)phosphoryl)octyl) ethanethioate (CAS 500573-41-1), a certified reference material (molecular formula C18H28NO6PS, MW 417.46 g/mol) for analytical method development and quality control.

Structurally, S-(8-(Ethoxy(4-nitrophenoxy)phosphoryl)octyl) ethanethioate (C18H28NO6PS) contains a steroid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 417.46 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.
