Chemical Structure

Atracurium Impurity 45 CAS CATO-C4X-185045 chemical structure

Description

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.

Atracurium Impurity 45 (CAS CATO-C4X-185045) is a certified pharmaceutical impurity reference standard with the molecular formula N/A and a molecular weight of N/A g/mol.

Atracurium Impurity 45 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).

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.
