Chemical Structure

Ensifentrine impurity 15 CAS CATO-C4X-335315 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 595.73 g/mol gives Ensifentrine impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ensifentrine impurity 15 (CAS CATO-C4X-335315) is a certified pharmaceutical impurity reference standard with the molecular formula C35H41N5O4 and a molecular weight of 595.73 g/mol.

Based on its molecular formula C35H41N5O4, Ensifentrine impurity 15 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 595.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Ensifentrine impurity 15 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.
