Irinotecan Impurity 61 CAS 14154-82-6

Description

Compared with other compounds in its class, the molecular weight of 276.81 g/mol gives Irinotecan Impurity 61 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Irinotecan Impurity 61 (CAS 14154-82-6), a pharmacopoeial impurity reference standard (molecular formula C13H24N2O2HCl, MW 276.81 g/mol) used for the identification and quantification of trace impurities in APIs.

Irinotecan Impurity 61 (C13H24N2O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
