Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dequalinium impurity 32.
Dequalinium impurity 32 (CAS CATO-C4X-193632) is a certified pharmaceutical impurity reference standard with the molecular formula C70H98N8 and a molecular weight of 1051.58 g/mol.
Dequalinium impurity 32 (C70H98N8) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Dequalinium impurity 32 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.
