Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1269.41 g/mol gives Terlipressin Impurity 28 X TFA Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Terlipressin Impurity 28 X TFA Salt (CAS CATO-C4X-219328) is a certified pharmaceutical impurity reference standard with the molecular formula C54H76N16O16S2 and a molecular weight of 1269.41 g/mol.
Structurally, Terlipressin Impurity 28 X TFA Salt (C54H76N16O16S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 1269.41 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
