Description
Vilanterol Impurity 24 Formate (CAS CATO-C4X-193524) is a certified pharmaceutical impurity reference standard with the molecular formula C36H53Cl2NO15CH2O2 and a molecular weight of 856.74 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Vilanterol Impurity 24 Formate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 856.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Vilanterol Impurity 24 Formate 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.
