Somatostatin Impurity 6 X TFA Salt CAS CATO-C4X-23506

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Somatostatin Impurity 6 X TFA Salt.

Somatostatin Impurity 6 X TFA Salt (CAS CATO-C4X-23506) is a certified pharmaceutical impurity reference standard with the molecular formula C76H103N18O18S2 and a molecular weight of 1620.87 g/mol.

Somatostatin Impurity 6 X TFA Salt (C76H103N18O18S2) 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 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.

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.
