Chemical Structure

Ropivacaine EP Impurity G ((R)-Ropivacaine) CAS 98717-16-9 chemical structure

Description

The occurrence of Ropivacaine EP Impurity G ((R)-Ropivacaine) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ropivacaine EP Impurity G ((R)-Ropivacaine) (CAS 98717-16-9) is a certified pharmaceutical impurity reference standard with the molecular formula C17H26N2O and a molecular weight of 274.40 g/mol.

Based on its molecular formula C17H26N2O, Ropivacaine EP Impurity G ((R)-Ropivacaine) contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 EP Impurity G ((R)-Ropivacaine) 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.
