Paliperidone Impurity 83 HCl CAS CATO-C4X-172483

Description

The occurrence of Paliperidone Impurity 83 HCl is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Paliperidone Impurity 83 HCl (CAS CATO-C4X-172483) is a certified pharmaceutical impurity reference standard with the molecular formula C12H14F2N2OHCl and a molecular weight of 276.71 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Paliperidone Impurity 83 HCl is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 276.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
