Vilanterol Impurity 68 CAS CATO-C4X-193568

Description

Compared with other compounds in its class, the molecular weight of 339.69 g/mol gives Vilanterol Impurity 68 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Vilanterol Impurity 68 (CAS CATO-C4X-193568), a pharmacopoeial impurity reference standard (molecular formula C15H21Cl3O2, MW 339.69 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Vilanterol Impurity 68 (C15H21Cl3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Vilanterol Impurity 68 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.
