Abrocitinib Impurity 1 CAS CATO-C4X-28841

Description

Compared with other compounds in its class, the molecular weight of 339.41 g/mol gives Abrocitinib Impurity 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Abrocitinib Impurity 1 (CAS CATO-C4X-28841) is a certified pharmaceutical impurity reference standard with the molecular formula C14H21N5O3S and a molecular weight of 339.41 g/mol.

The molecular framework of Abrocitinib Impurity 1 (C14H21N5O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Abrocitinib Impurity 1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
