Droxidopa Impurity 2 CAS 5707-55-1 chemical structure

Description

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 process- or degradation-related impurity, Droxidopa Impurity 2 (CAS 5707-55-1, C8H8O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C8H8O3, Droxidopa Impurity 2 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 152.15 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).

CATO manufactures Droxidopa Impurity 2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
