2-(8-Methyl-2,4-dioxo-1,3-diazaspiro[4.5]decan-3-yl)-N-(2-(thiophen-2-yl)ethyl)acetamide CAS 923685-11-4

Description

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.

CATO supplies 2-(8-Methyl-2,4-dioxo-1,3-diazaspiro[4.5]decan-3-yl)-N-(2-(thiophen-2-yl)ethyl)acetamide (CAS 923685-11-4), a certified reference material (molecular formula C17H23N3O3S, MW 349.45 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(8-Methyl-2,4-dioxo-1,3-diazaspiro[4.5]decan-3-yl)-N-(2-(thiophen-2-yl)ethyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
