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-β]pyridin-5(4H)-one.
1H-Pyrrolo[3,2-β]pyridin-5(4H)-one (CAS 17322-91-7), molecular formula C7H6N2O and molecular weight 134.14 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H6N2O, 1H-Pyrrolo[3,2-β]pyridin-5(4H)-one contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 134.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
