Liraglutide Impurity 16 TFA Salt CAS CATO-C4X-199216

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Liraglutide Impurity 16 TFA Salt.

CATO supplies Liraglutide Impurity 16 TFA Salt (CAS CATO-C4X-199216), a pharmacopoeial impurity reference standard (molecular formula C85H132N16O22, MW 1730.05 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Liraglutide Impurity 16 TFA Salt (C85H132N16O22) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 1730.05 g/mol, it falls into the high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
