Description

Compared with other compounds in its class, the molecular weight of 194.15 g/mol gives 3-Amino-4-hydroxy-1H-pyrazolo[4,3-c]pyridine-7-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Amino-4-hydroxy-1H-pyrazolo[4,3-c]pyridine-7-carboxylic acid (CAS 120581-76-2), molecular formula C7H6N4O3 and molecular weight 194.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Amino-4-hydroxy-1H-pyrazolo[4,3-c]pyridine-7-carboxylic acid (C7H6N4O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. 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.
