    Pure anhydrous caffeine is a bitter-tasting, white, odorless powder with a melting point of 235–238 °C. [7] [8] Caffeine is moderately soluble in water at room temperature (2 g/100 mL), but quickly soluble in boiling water (66 g/100 mL). [197] It is also moderately soluble in ethanol (1.5 g/100 mL).

    For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. [13] Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than ...
