Product Name:5-chloro-3-hydroxyisothiazole
CAS Number:25629-58-7
Molecular formula:C3H2ClNOS
Molecular Weight:135.57

5-chloro-3-hydroxyisothiazole can be synthesized from 3,3'-disulfanediyldipropionic acid and Thionyl chloride in three steps. In particular, in the last step, 5-chloro isothiazolone derivatives (5-chloro-3-hydroxyisothiazole) were the predominant products when the ratio of sulfuryl chloride/amide was 3:1 while with the relevant ratio of 1:1, the 5-unsubstituted analogs were the predominant products[1].
