Chemical Structure

Ropivacaine Impurity 34 CAS 175888-75-2 chemical structure

Description

As a process- or degradation-related impurity, Ropivacaine Impurity 34 (CAS 175888-75-2, C17H26N2O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Ropivacaine Impurity 34 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.40 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).

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 Ropivacaine Impurity 34 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.
