Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Liraglutide Impurity 13 TFA Salt.
CATO supplies Liraglutide Impurity 13 TFA Salt (CAS CATO-C4X-199213), a pharmacopoeial impurity reference standard (molecular formula C35H63N5O10, MW 713.90 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Liraglutide Impurity 13 TFA Salt is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 713.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Liraglutide Impurity 13 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.
