Description
CATO supplies Bortezomib Impurity N34 TFA salt (CAS 2363753-29-9), a pharmacopoeial impurity reference standard (molecular formula C15H28BNO2C2HF3O2, MW 379.23 g/mol) used for the identification and quantification of trace impurities in APIs.
Bortezomib Impurity N34 TFA salt (C15H28BNO2C2HF3O2) contains an amide group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Bortezomib Impurity N34 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.
