Chemical Structure
Description
Based on its molecular formula C12H22N2O, 7-methylpyrazolo[1,5-a]quinolin-3-ol contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 210.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
7-methylpyrazolo[1,5-a]quinolin-3-ol (CAS 2766427-69-2) is a high-purity analytical reference standard with the molecular formula C12H22N2O and a molecular weight of 210.32 g/mol.
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.
