Terlipressin Impurity 23 CAS CATO-C4X-219323

Description

Compared with other compounds in its class, the molecular weight of 2437.71 g/mol gives Terlipressin Impurity 23 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Terlipressin Impurity 23 (CAS CATO-C4X-219323) is a certified pharmaceutical impurity reference standard with the molecular formula C104H145N31O30S4 and a molecular weight of 2437.71 g/mol.

Terlipressin Impurity 23 (C104H145N31O30S4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
