Physical and Chemical Properties | Sodium methanethiol is the sodium salt of methanethiol with the formula CH3SNa. Its aqueous solution is light yellow red transparent liquid, odor, for strong alkaline liquid, can be used as raw materials of pesticide, medicine, dye intermediate. It can be oxidized to dimethyl disulfide (CH3SSCH3) by iodine and analyzed accordingly. Methyl mercaptan sodium reacts with sulfuric acid to form methyl mercaptan. Methyl mercaptan sodium is an important organic intermediate compound, such as used as pesticide grass net, methomyl and organic intermediate raw material; Food additive methionine, Vitamin U, rubber vulcanizing agent raw material; Antidote of hydrogen sulfide poisoning; gas, natural gas odor, etc. Sodium methyl mercaptan is dangerous goods, belonging to the main risk of Class 8 corrosive and secondary risk of class 4.1 Flammable solids, export need to operate in accordance with the regular dangerous goods, normal can be sent by sea, air and international express. |
Use | Can be used as raw materials of pesticide, medicine, dye intermediates |

Use | Sodium methyl mercaptan is used as a strong nucleophile to synthesize methyl aryl sulfide from halogenated aromatic hydrocarbons. Alkanethiolate is an effective reagent for SN 2 dealkylation of esters and aryl ethers. Sodium methylmercaptan can be used in the dye, pharmaceutical and pesticide industries, and can be used in the manufacture of methionine and methomyl. It can be used as a raw material for pesticides, medicines, and dye intermediates |
