Ruxolitinib Impurity 79 CAS 941678-60-0 chemical structure

Description

As a certified reference material (CRM), Ruxolitinib Impurity 79 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.

Ruxolitinib Impurity 79 (CAS 941678-60-0) is a certified pharmaceutical impurity reference standard with the molecular formula C17H16N6 and a molecular weight of 304.35 g/mol.

Ruxolitinib Impurity 79 (C17H16N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
