Chemical Structure

Phenylephrine Impurity 43 CAS 2300752-10-5 chemical structure

Description

The occurrence of Phenylephrine Impurity 43 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Phenylephrine Impurity 43 (CAS 2300752-10-5) is a certified pharmaceutical impurity reference standard with the molecular formula C15H15NO2 and a molecular weight of 241.29 g/mol.

Based on its molecular formula C15H15NO2, Phenylephrine Impurity 43 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 241.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Phenylephrine Impurity 43 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.
