Chemical Structure

Oxaliplatin EP Impurity E CAS 82398-34-3 chemical structure

Description

Structurally, Oxaliplatin EP Impurity E (C12H30N4O2Pt2NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 714.56 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Oxaliplatin EP Impurity E (CAS 82398-34-3) is a certified pharmaceutical impurity reference standard with the molecular formula C12H30N4O2Pt2NO3 and a molecular weight of 714.56 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.
