Voriconazole Impurity 61 CAS CATO-C4X-136661

Description

The occurrence of Voriconazole Impurity 61 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Voriconazole Impurity 61 (CAS CATO-C4X-136661), a pharmacopoeial impurity reference standard (molecular formula C16H13ClF3N5O, MW 383.76 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Voriconazole Impurity 61 (C16H13ClF3N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 383.76 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Voriconazole Impurity 61 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.
