4-(4-Fluorophenyl)-5-(methoxymethyl)-2,6-bis(1-methylethyl)-3-pyridinecarboxylic Acid Methyl Ester 887407-03-6 Methyl 2,6-Diisopropyl-4-(4-fluorophenyl)-3-hydroxymethyl-5-methoxypyridine-3-carboxylate (CAS 887407-03-6), molecular formula C21H26FNO3 and molecular weight 359.43 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H26FNO3, 4-(4-Fluorophenyl)-5-(methoxymethyl)-2,6-bis(1-methylethyl)-3-pyridinecarboxylic Acid Methyl Ester 887407-03-6 Methyl 2,6-Diisopropyl-4-(4-fluorophenyl)-3-hydroxymethyl-5-methoxypyridine-3-carboxylate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 359.43 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.
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.
