“…MS/MS coupled with HPLC (high‐performance liquid chromatography) is the analytical technique of choice for most assays used during the discovery of new drugs (Appolonova, Dikunets, & Rodchenkov, 2008; Mesonzhnik et al, 2018; Moskaleva, Baranov, Mesonzhnik, & Appolonova, 2017; Shpak, Appolonova, & Semenov, 2005; Zherdev et al, 2009).
