解或变质。硫胺可以溶于水，不溶于醇等有机溶剂。常温下在pH为3.5的水溶液中稳定，而在中性和碱性溶液中会发生分解。通常会被制作为盐酸盐（C12H18Cl2N4OS，CAS No.67-03-8）、硝酸盐（C12H17N5O4S，CAS No.532-43-4）等较稳定的形式来使用。 　　
硫胺的发现和脚气病成因的探索密切相关，脚气病是一种曾经在亚洲地区较普遍的维生素缺乏症，症状有下肢浮肿等。

1、维生素B1缺乏时，可引起多种神经炎症，如脚气病菌。维生素B1缺乏所引起的多发性神经炎，患者的周围神经末梢有发炎和退化现象，并伴有四肢麻木、肌肉萎缩、心力衰竭、下肢水肿等症状；
2、维生素B1缺乏常由于摄入不足，需要量增高和吸收利用障碍。肝损害、饮酒也可引起。长期透析的肾病者、完全胃肠外营养的病人以及长期慢性发热病人都可发生。初期症状，有疲乏、淡漠、食欲差、恶心、忧郁、急躁、沮丧、腿麻林和心电图异常。一般分成几类：干性脚气病，湿性脚气病，婴儿脚气病。
