Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 502.96 g/mol gives Nafamostat Impurity 13 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Nafamostat Impurity 13 HCl (CAS CATO-C4X-133223), a pharmacopoeial impurity reference standard (molecular formula C26H22N6O3HCl, MW 502.96 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Nafamostat Impurity 13 HCl (C26H22N6O3HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 502.96 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 13 HCl 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.
