Chemical Structure

Dimemorfan Phosphate Impurity 11 CAS CATO-C4X-335811 chemical structure

Description

CATO supplies Dimemorfan Phosphate Impurity 11 (CAS CATO-C4X-335811), a pharmacopoeial impurity reference standard (molecular formula C18H25N, MW 255.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H25N, Dimemorfan Phosphate Impurity 11 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 255.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
