Chemical Structure

Nafamostat impurity 125 CAS 1553717-68-2 chemical structure

Description

As a certified reference material (CRM), Nafamostat impurity 125 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.

Nafamostat impurity 125 (CAS 1553717-68-2) is a certified pharmaceutical impurity reference standard with the molecular formula C11H10N2O and a molecular weight of 186.21 g/mol.

The molecular framework of Nafamostat impurity 125 (C11H10N2O) 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 its high hydrophobicity (logP), 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
