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-benzyl-4-chloro-2H-pyrazolo[4,3-c]pyridine (CAS 41372-95-6), molecular formula C13H24ClN3 and molecular weight 257.80 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, 2-benzyl-4-chloro-2H-pyrazolo[4,3-c]pyridine is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 257.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
