Chemical Structure

Piperacillin EP Impurity J CAS 2170771-47-6 chemical structure

Description

The occurrence of Piperacillin EP Impurity J is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Piperacillin EP Impurity J (CAS 2170771-47-6) is a certified pharmaceutical impurity reference standard with the molecular formula C17H20N4O6 and a molecular weight of 376.36 g/mol.

The molecular framework of Piperacillin EP Impurity J (C17H20N4O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
