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 1H-Pyrrolo[3,2-c]pyridin-2(3H)-one hydrochloride.
1H-Pyrrolo[3,2-c]pyridin-2(3H)-one hydrochloride (CAS 1956321-64-4), molecular formula C7H6N2OHCl and molecular weight 170.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1H-Pyrrolo[3,2-c]pyridin-2(3H)-one hydrochloride (C7H6N2OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
