Chemical Structure
Description
The occurrence of (S)-[1-[(cyclohexyl[(cyclohexylamino)carbonyl]amino)carbonyl]-2-methylpropyl]-Carbamic acid phenylmethyl ester is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (S)-[1-[(cyclohexyl[(cyclohexylamino)carbonyl]amino)carbonyl]-2-methylpropyl]-Carbamic acid phenylmethyl ester (CAS 53111-06-1), a certified reference material (molecular formula C26H45N3O4, MW 463.65 g/mol) for analytical method development and quality control.
(S)-[1-[(cyclohexyl[(cyclohexylamino)carbonyl]amino)carbonyl]-2-methylpropyl]-Carbamic acid phenylmethyl ester (C26H45N3O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
