Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Vortioxetine Impurity 118.
CATO supplies Vortioxetine Impurity 118 (CAS 94041-16-4), a pharmacopoeial impurity reference standard (molecular formula C44H32O2P2, MW 654.67 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Vortioxetine Impurity 118 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 654.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
