Atracurium Impurity 37 CAS CATO-C4X-185037

Description

Compared with other compounds in its class, the molecular weight of 601.71 g/mol gives Atracurium Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Atracurium Impurity 37 (CAS CATO-C4X-185037) is a certified pharmaceutical impurity reference standard with the molecular formula C25H34NO6C6H5O3S and a molecular weight of 601.71 g/mol.

The molecular framework of Atracurium Impurity 37 (C25H34NO6C6H5O3S) 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.

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.

As a certified reference material (CRM), Atracurium Impurity 37 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.
