Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5'H-spiro[piperidine-4,4'-pyrrolo[1,2-a]quinoxaline]-7'-carboxylate hydrochloride.
CATO supplies Methyl 5'H-spiro[piperidine-4,4'-pyrrolo[1,2-a]quinoxaline]-7'-carboxylate hydrochloride (CAS 1242268-06-9), a certified reference material (molecular formula C17H19N3O2HCl, MW 333.82 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl 5'H-spiro[piperidine-4,4'-pyrrolo[1,2-a]quinoxaline]-7'-carboxylate hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
