Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tert-butyl 4-(2-oxo-1,3,8-triazaspiro[4.5]Decan-3-yl)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.41 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).
CATO supplies Tert-butyl 4-(2-oxo-1,3,8-triazaspiro[4.5]Decan-3-yl)benzoate (CAS 2055882-75-0), a certified reference material (molecular formula C18H25N3O3, MW 331.41 g/mol) for analytical method development and quality control.
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.
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.
