Chemical Structure
Description
Rizatriptan Dimer Impurity 3 (CAS 1016900-25-6), molecular formula C28H35N7C7H6O2 and molecular weight 591.76 g/mol, is a CATO reference standard with documented purity and traceability.
Rizatriptan Dimer Impurity 3 (C28H35N7C7H6O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Rizatriptan Dimer Impurity 3 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.
