Chemical Structure
Description
Based on its molecular formula C8H7N3O2HCl, 2-{1H-pyrazolo[4,3-b]pyridin-1-yl}acetic acid dihydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 213.62 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).
2-{1H-pyrazolo[4,3-b]pyridin-1-yl}acetic acid dihydrochloride (CAS 1803585-64-9), molecular formula C8H7N3O2HCl and molecular weight 213.62 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
