Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2-Hydroxyethoxy)-3-aminopyrazolo[1,5-a]pyridine hydrochloride (CAS 1079221-49-0), molecular formula C9H19N3O2HCl and molecular weight 237.73 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H19N3O2HCl, 2-(2-Hydroxyethoxy)-3-aminopyrazolo[1,5-a]pyridine hydrochloride contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 237.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
