Description
CATO manufactures Cyanocobalamin Impurity 29 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.
CATO supplies Cyanocobalamin Impurity 29 (CAS 23388-02-5 (unfixed chirality)), a pharmacopoeial impurity reference standard (molecular formula C63H86CoN14O14P, MW 1353.35 g/mol) used for the identification and quantification of trace impurities in APIs.
Cyanocobalamin Impurity 29 (C63H86CoN14O14P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester 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).
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.
