Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 2440.67 g/mol gives Terlipressin Impurity 21 X TFA Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Terlipressin Impurity 21 X TFA Salt (CAS CATO-C4X-219321) is a certified pharmaceutical impurity reference standard with the molecular formula C104H142N28O33S4 and a molecular weight of 2440.67 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Terlipressin Impurity 21 X TFA Salt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 2440.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
CATO manufactures Terlipressin Impurity 21 X TFA Salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
