Quantification of water solubility of DMCU, 1-TFA, and 2-TFA. (A,B) Mass spectrum (A) and extracted ion chromatograms (XIC) (B) of DMCU, 1-TFA, and 2-TFA. (C–E) Calibration curves of DMCU (C), 1-TFA (D), and 2-TFA (E). (F) An investigation on the water solubility of DMCU. The solubility of all compounds was determined at room temperature.
