Chemical Structure

Terlipressin Impurity 26 X TFA Salt CAS CATO-C4X-219326 chemical structure

Description

The occurrence of Terlipressin Impurity 26 X TFA Salt is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Terlipressin Impurity 26 X TFA Salt (CAS CATO-C4X-219326), a pharmacopoeial impurity reference standard (molecular formula C54H76N16O16S2, MW 1269.41 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C54H76N16O16S2, Terlipressin Impurity 26 X TFA Salt contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1269.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
