Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Eucatropine Impurity 1 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Eucatropine Impurity 1 (CAS CATO-C4X-32211) is a certified pharmaceutical impurity reference standard with the molecular formula C17H23NO4 and a molecular weight of 305.37 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.
CATO manufactures Eucatropine Impurity 1 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.
