Atrasentan Impurity 89 CAS 1059043-39-8

Description

Compared with other compounds in its class, the molecular weight of 636.87 g/mol gives Atrasentan Impurity 89 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Atrasentan Impurity 89 (CAS 1059043-39-8), a pharmacopoeial impurity reference standard (molecular formula C38H56N2O6, MW 636.87 g/mol) used for the identification and quantification of trace impurities in APIs.

Atrasentan Impurity 89 (C38H56N2O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.

As a certified reference material (CRM), Atrasentan Impurity 89 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.
