Chemical Structure

Abrocitinib Impurity 36 CAS CATO-C4X-288436 chemical structure

Description

The occurrence of Abrocitinib Impurity 36 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Abrocitinib Impurity 36 (CAS CATO-C4X-288436), a pharmacopoeial impurity reference standard (molecular formula C14H20ClN5O2S, MW 357.86 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Abrocitinib Impurity 36 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Abrocitinib Impurity 36 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.
