Chemical Structure

Nafamostat Impurity 18 CAS 52805-47-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nafamostat Impurity 18.

CATO supplies Nafamostat Impurity 18 (CAS 52805-47-7), a pharmacopoeial impurity reference standard (molecular formula C11H7NO, MW 169.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Nafamostat Impurity 18 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 169.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Nafamostat Impurity 18 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.
