用途紫外線吸収剤、有機合成原料。
純化方法Recrystallise the acid from *C6H6 or cyclohexane, but it is best recrystallised by dissolving in a small volume of hot toluene and then adding just enough pet ether to cause turbidity, and cool. Dry it in a low vacuum at 80o. It can be sublimed at 230-240o/0.3mm [Bray et al. J Chem Soc 265 1957]. The S-benzylisothiuronium salt has m 177-178o (from EtOH). [Lewenz & Serijan J Am Chem Soc 75 4087 1953, Beilstein 10 H 747, 10 IV 2977.]
