The occurrence of Landiolol Impurity 52 1/2 Oxalate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Landiolol Impurity 52 1/2 Oxalate (CAS CATO-C4X-262152), a pharmacopoeial impurity reference standard (molecular formula C23H33N3O7C2H2O4, MW 553.56 g/mol) used for the identification and quantification of trace impurities in APIs.
Landiolol Impurity 52 1/2 Oxalate (C23H33N3O7C2H2O4) contains a flavonoid core, 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).
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.
As a certified reference material (CRM), Landiolol Impurity 52 1/2 Oxalate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
