Chemical Structure

Metaraminol Impurity 15 CAS 13103-80-5 chemical structure

Description

Metaraminol Impurity 15 (C9H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Metaraminol Impurity 15 (CAS 13103-80-5) is a certified pharmaceutical impurity reference standard with the molecular formula C9H10O2 and a molecular weight of 150.17 g/mol.

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), Metaraminol 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.
