异丙硫醇(Isopropanethiol),又称为2-丙硫醇,是一种硫醇类的有机化合物。它是醇的一种类似物,结构就是异丙醇取代。异丙硫醇是一种闪点易燃的无色液体,具有挥发性,微量具有臭味,对身体有害,大量吸入会引起嗅觉丧失、肌无力等症状。口服引起恶心、呕吐。对眼和皮肤有刺激性。

毒性

异丙硫醇和异丙醇有类似性质,同样有剧毒[来源请求],异丙硫醇的毒性甚至比异丙醇更强。

吸入微量异丙硫醇,会感到恶臭,并且轻微刺激呼吸道。若在高浓度的环境下,会造成肌肉无力、惊厥、呼吸麻痹、丧失嗅觉、晕眩、甚至昏迷的严重症状。误食异丙硫醇会造成晕眩、恶心、呕吐,严重者意识丧失甚至死亡。

若发现吸入异丙硫醇之病患,就同于吸入异丙醇的病患,应先移除污染源或将患者移到新鲜空气处。倘若患者停止呼吸应立即施予人工呼吸后再就医。

若发现误食异丙硫醇者,应先给病患服用大量的水后再送医治疗。
