Axitinib Impurity 37 CAS CATO-C4X-107137

Description

Compared with other compounds in its class, the molecular weight of 162.15 g/mol gives Axitinib Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Axitinib Impurity 37 (CAS CATO-C4X-107137), a pharmacopoeial impurity reference standard (molecular formula C7H6N4O, MW 162.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, Axitinib Impurity 37 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.15 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), Axitinib Impurity 37 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.
