Chemical Structure

1-(4-Nitrophenyl)-2',3',4',9'-tetrahydrospiro[piperidine-4,1'-pyrido[3,4-b]indole] hydrochloride CAS 317822-52-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 398.89 g/mol gives 1-(4-Nitrophenyl)-2',3',4',9'-tetrahydrospiro[piperidine-4,1'-pyrido[3,4-b]indole] hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(4-Nitrophenyl)-2',3',4',9'-tetrahydrospiro[piperidine-4,1'-pyrido[3,4-b]indole] hydrochloride (CAS 317822-52-9), a certified reference material (molecular formula C21H22N4O2HCl, MW 398.89 g/mol) for analytical method development and quality control.

Based on its molecular formula C21H22N4O2HCl, 1-(4-Nitrophenyl)-2',3',4',9'-tetrahydrospiro[piperidine-4,1'-pyrido[3,4-b]indole] 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 398.89 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
