Crisaborole Impurity 62 CAS CATO-C4X-202162

Description

Compared with other compounds in its class, the molecular weight of 253.25 g/mol gives Crisaborole Impurity 62 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Crisaborole Impurity 62 (CAS CATO-C4X-202162), a pharmacopoeial impurity reference standard (molecular formula C15H11NO3, MW 253.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Crisaborole Impurity 62 (C15H11NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 253.25 g/mol, it falls into the medium-molecular-weight range. 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), Crisaborole Impurity 62 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.
