B. p. 254 to 255°, 131 to 133° (12 to 13 mm.); d15o 1,067.1) B. p. 107 to 109° (4 mm.); d15o 1,0690; nD20o1,54134.2)
In a freezing mixture it congeals to a crystalline mass which melts at + 8,5°.
For its identification the benzoyl compound, m. p. 49 to 50° is utilized. The acetyl compound melts at - 5°; b. p. 275 to 277°.
In alcoholic solution, betelphenol gives an intensively blue-green color with ferric chloride.
