Chemical Structure

Etilefrine Impurity 3 CAS CATO-C4X-27733 chemical structure

Description

The occurrence of Etilefrine Impurity 3 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Etilefrine Impurity 3 (CAS CATO-C4X-27733) is a certified pharmaceutical impurity reference standard with the molecular formula C10H15NO5S and a molecular weight of 261.29 g/mol.

Etilefrine Impurity 3 (C10H15NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Etilefrine Impurity 3 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.
