Chemical Structure

Potassium Clavulanate EP Impurity L CAS 4013-94-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 144.26 g/mol gives Potassium Clavulanate EP Impurity L distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Potassium Clavulanate EP Impurity L (CAS 4013-94-9, C8H20N2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

The molecular framework of Potassium Clavulanate EP Impurity L (C8H20N2) is characterized by an organic framework. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
