Chemical Structure

Treprostinil Impurity 5 CAS CATO-C4X-21165 chemical structure

Description

Structurally, Treprostinil Impurity 5 (C46H66O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 763.01 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Treprostinil Impurity 5 (CAS CATO-C4X-21165) is a certified pharmaceutical impurity reference standard with the molecular formula C46H66O9 and a molecular weight of 763.01 g/mol.

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.
