The IUPAC name of n-Butyl methyl sulphide is 1-methylsulfanylbutane . With the CAS registry number 628-29-5, it is also named as Butane, 1-(methylthio)- ; Methyl butyl sulphide ; Butyl methyl sulphide . n-Butyl methyl sulphide is highly flammable. Keep away from sources of ignition. Do not breathe vapour. Take precautionary measures against static discharges.

Many organic reaction can generate n-Butyl methyl sulphide . Such as: 1. 4-chloro-benzoic acid methyl ester can recats with tris-methylsulfanyl-methane to get tetrathioorthocarbonic acid tetramethyl ester , 1-(4-chloro-phenyl)-2,2-bis-methylsulfanyl-ethanone and 1-methylsulfanyl-butane . 2. 1-methyl-tetrahydro-thiophenium can generate methane , 1-methylsulfanyl-butane and tetrahydrothiophene .

The n-Butyl methyl sulphide can be used in organic synthesis to obtain other chemicals. For example: 1. It can react with azidobenzene to get 2-butylsulfanyl-aniline.

2. It also reacts with benzenesulfonic acid to get N-Phenylsulfonyl-S-butyl-S-methylsulfilimine .
