Bitter taste. pH (saturated solution in water): 5.5-7. Air & Water Reactions Insoluble in water. Reactivity Profile Theobromine may be sensitive to prolonged exposure to light. Theobromine has weakly acidic properties, combining with bases to forms salts. Theobromine also has even weaker basic properties, combining with acids to form salts which are decomposed in aqueous solution. . Fire Hazard Flash point data for Theobromine are not available; however, Theobromine is probably combustible.
