Acetylcysteine EP Impurity C CAS 5545-17-5

Description

Compared with other compounds in its class, the molecular weight of 324.37 g/mol gives Acetylcysteine EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Acetylcysteine EP Impurity C (CAS 5545-17-5) is a certified pharmaceutical impurity reference standard with the molecular formula C10H16N2O6S2 and a molecular weight of 324.37 g/mol.

The molecular framework of Acetylcysteine EP Impurity C (C10H16N2O6S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Acetylcysteine EP Impurity C meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
