Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 202.14 g/mol gives Ropivacaine Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ropivacaine Impurity 9 (CAS 13388-86-8), molecular formula C8H11O4P and molecular weight 202.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ropivacaine Impurity 9 (C8H11O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Ropivacaine Impurity 9 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.
