Chemical Structure

Cisatracurium Besilate EP Impurity D 3/2 Besylate CAS CATO-C4X-185093 chemical structure

Description

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.

As a process- or degradation-related impurity, Cisatracurium Besilate EP Impurity D 3/2 Besylate (CAS CATO-C4X-185093, N/A) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Cisatracurium Besilate EP Impurity D 3/2 Besylate is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
