Chemical Structure

Ropivacaine Impurity 35 CAS 2180-94-1 chemical structure

Description

Structurally, Ropivacaine Impurity 35 (C16H24N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 260.37 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies Ropivacaine Impurity 35 (CAS 2180-94-1), a pharmacopoeial impurity reference standard (molecular formula C16H24N2O, MW 260.37 g/mol) used for the identification and quantification of trace impurities in APIs.

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), Ropivacaine Impurity 35 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.
