Description
CATO supplies Upadacitinib Impurity 77 (CAS 2050038-84-9), a pharmacopoeial impurity reference standard (molecular formula C14H17N5HCl, MW 291.78 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Upadacitinib Impurity 77 (C14H17N5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 291.78 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.
CATO manufactures Upadacitinib Impurity 77 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
