Two physical properties of the fluorinated carboxylic acid, 2H-hexadecafluoro-2-decenoic acid (C10F16H2O2), were investigated in this study: melting point and solubility. Melting point data were ascertained on a traditional melting point apparatus and a differential scanning calorimeter (DSC), while solubility data were obtained using an LC-MS/MS system. A melting point of 105 +/- 1 degrees C and an aqueous solubility of 64 +/- 5 ng/mu L at ambient temperatures were observed.
