Chemical Structure

Endo-Asn8a-Terlipressin CAS CATO-C4X-219335 chemical structure

Description

CATO supplies Endo-Asn8a-Terlipressin (CAS CATO-C4X-219335), a certified reference material (molecular formula C56H80N18O17S2, MW 1341.47 g/mol) for analytical method development and quality control.

Endo-Asn8a-Terlipressin (C56H80N18O17S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
