5-Nitro-1h,2h,3h-pyrazolo[3,4-b]pyridin-3-one CAS 1186609-73-3

Description

The occurrence of 5-Nitro-1h,2h,3h-pyrazolo[3,4-b]pyridin-3-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Nitro-1h,2h,3h-pyrazolo[3,4-b]pyridin-3-one (CAS 1186609-73-3), a certified reference material (molecular formula C6H4N4O3, MW 180.12 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H4N4O3, 5-Nitro-1h,2h,3h-pyrazolo[3,4-b]pyridin-3-one contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 180.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
