Clozapine impurity 8 CAS 5814-41-5

Description

Compared with other compounds in its class, the molecular weight of 210.23 g/mol gives Clozapine impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Clozapine impurity 8 (CAS 5814-41-5), a pharmacopoeial impurity reference standard (molecular formula C13H10N2O, MW 210.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Clozapine impurity 8 (C13H10N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
