3,5-Dimethylbenzenethiol is an organic building block. It is also referred to as 5-mercapto-m-xylene.3,5-Dimethylbenzenethiol may be employed as a starting reagent in the preparation of Lithium 2-lithio-3,5-dimethylbenzenethiolate. It may also be used in the preparation of 1,1,2-trichloro-4-(3,5-dimethylphenylthio)-1-buten-3-yne and 1,1,2,4-tetrachloro-4-(3,5-dimethylphenylthio)-1,3-butadiene. 3,5-Dimethylbenzenethiol is an organic building block.
