Chemical Structure
Description
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.
(3S,4S)-4-[(1R)-Phenylethylamino-3-methoxycarbonyl]-2,2,6,6-tetramethylpiperidine-1-oxyl Hydrochloride (CAS 583827-06-9), molecular formula C19H30N2O3HCl and molecular weight 370.92 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H30N2O3HCl, (3S,4S)-4-[(1R)-Phenylethylamino-3-methoxycarbonyl]-2,2,6,6-tetramethylpiperidine-1-oxyl Hydrochloride contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 370.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
