Chemical Structure

Levodopa Impurity 23 CAS 75290-51-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 215.18 g/mol gives Levodopa Impurity 23 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Levodopa Impurity 23 (CAS 75290-51-6, C9H10FNO4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Levodopa Impurity 23 (C9H10FNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Levodopa Impurity 23 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.
