1,3-二噻烷2位的亚甲基氢具有较高的酸度（pKa31.1），在烷基锂等强碱作用下可生成烷基阴离子物种。由于硫缩醛通过脱保护转化为羰基，1,3-二噻烷可用作酰基阴离子等价物（酰基极性改变）。也就是说，酮醛可以通过使亲核试剂如卤代烷反应然后将产物水解来获得。它也可以通过脱硫反应转化为烷烃。
1,3-Dithiane is a protected formaldehyde anion equivalent that could serve as a useful labeled synthon[1]. 1,3-Dithiane is also a sulfur-containing Maillard reaction products (MRPs) found in boiled beef extracts. 1,3-Dithiane shows a potent direct-acting mutagenicity toward S. typhimurium TA98 and TA100[2].
