Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 1-(4-chlorophenyl)-3-methyl-4-((3-(trifluoromethyl)benzyl)amino)-1H-pyrazolo[3,4-b]pyridine-5-carboxylate.
Ethyl 1-(4-chlorophenyl)-3-methyl-4-((3-(trifluoromethyl)benzyl)amino)-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (CAS 866132-88-9), molecular formula C24H20ClF3N4O2 and molecular weight 488.89 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C24H20ClF3N4O2, Ethyl 1-(4-chlorophenyl)-3-methyl-4-((3-(trifluoromethyl)benzyl)amino)-1H-pyrazolo[3,4-b]pyridine-5-carboxylate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 488.89 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).
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.
