Description
CATO supplies rac-Adrenaline EP Impurity D TFA salt (CAS 1095714-91-2(Free Base)), a pharmacopoeial impurity reference standard (molecular formula C16H19NO3C2HF3O2, MW 387.35 g/mol) used for the identification and quantification of trace impurities in APIs.
rac-Adrenaline EP Impurity D TFA salt (C16H19NO3C2HF3O2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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 supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), rac-Adrenaline EP Impurity D TFA salt 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.
