Description
CATO supplies Pitolisant impurity 31 (CAS CATO-C4X-252031), a pharmacopoeial impurity reference standard (molecular formula C12H16Cl2O, MW 247.16 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Pitolisant impurity 31 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 247.16 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 Pitolisant impurity 31 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.
