Description
Encorafenib Impurity 11 (CAS CATO-C4X-324911) is a certified pharmaceutical impurity reference standard with the molecular formula C15H22N6O2 and a molecular weight of 318.37 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Encorafenib Impurity 11 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Encorafenib Impurity 11 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.
