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.
Spiro[piperidine-4,3'-pyrrolo[2,3-b]pyridin]-2'(1'H)-one hydrochloride (CAS 1038866-43-1) is a high-purity analytical reference standard with the molecular formula C11H13N3OHCl and a molecular weight of 239.70 g/mol.
The molecular framework of Spiro[piperidine-4,3'-pyrrolo[2,3-b]pyridin]-2'(1'H)-one hydrochloride (C11H13N3OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
