Proparacaine Impurity 14 CAS CATO-C4X-202714

Description

Compared with other compounds in its class, the molecular weight of 252.31 g/mol gives Proparacaine Impurity 14 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Proparacaine Impurity 14 (CAS CATO-C4X-202714), a pharmacopoeial impurity reference standard (molecular formula C13H20N2O3, MW 252.31 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Proparacaine Impurity 14 (C13H20N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Proparacaine Impurity 14 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.
