Chemical Structure

Upadacitinib Impurity 189 2HCl CAS CATO-C4X-2405189 chemical structure

Description

The occurrence of Upadacitinib Impurity 189 2HCl is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Upadacitinib Impurity 189 2HCl (CAS CATO-C4X-2405189) is a certified pharmaceutical impurity reference standard with the molecular formula C16H23N5HCl and a molecular weight of 321.85 g/mol.

Based on its molecular formula C16H23N5HCl, Upadacitinib Impurity 189 2HCl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 321.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Upadacitinib Impurity 189 2HCl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
