Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1H-Cyclopenta[3,4]pyrazolo[1,5-a]pyridine (CAS 103570-62-3), molecular formula C10H8N2 and molecular weight 156.18 g/mol, is a CATO reference standard with documented purity and traceability.
1H-Cyclopenta[3,4]pyrazolo[1,5-a]pyridine (C10H8N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
