Chemical Structure

Peficitinib Impurity 21 CAS CATO-C4X-280721 chemical structure

Description

Peficitinib Impurity 21 (CAS CATO-C4X-280721) is a certified pharmaceutical impurity reference standard with the molecular formula C10H17NOHCl and a molecular weight of 203.71 g/mol.

Based on its molecular formula C10H17NOHCl, Peficitinib Impurity 21 contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 203.71 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.

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.
