Thioacetamide Chemical Properties,Uses,Production

Organic reagents

Thioacetamide is organic reagent, it is colorless or white crystalline flake. It is dissolved in water, ethanol, very slightly soluble in benzene, ether, the aqueous solution at room temperature or 50~60℃ is fairly stable, when placed 2 to 3 weeks, it is not change, but when hydrogen ions is in the presence, it quickly decomposes into hydrogen sulfide , but hydrolysis increases with alkalinity or acidity of the solution and the temperature rises quickly. Hydrolysis equations solution of thioacetamide in acidic and basic is:
Acidic solution: CH3CSNH2 + 2H2O----(NH4 +) + CH3COO-+ H2S
Alkaline solution: CH3CSNH2 + 2OH-----NH3 + CH3COO-+ HS-
Since H2S or HS-can generate for hydrolysis in acidic or alkaline solution, so in analytical chemistry, it is often used in place of toxic and odor H2S, as the metal cation group reagents or precipitation reagents. The property of resulting precipitate is good, easy to separate. In addition, it can also be used for bismuth measurement reagent. Preparation method: It can be prepared by heating the acetamide with aluminum sulfide, hydrogen sulfide reacting with acetonitrile, or acetamide reacting with K3PS4.

Chemical properties

It is colorless or white crystals. Mp is 113-114℃, the solubility in water is 16.3g/100ml at 25℃, ethanol 26.4g/100ml. It is slightly soluble in benzene, ether. Their solution is quite stable at room temperature or 50-60℃, but when hydrogen ions exists, it can generate thiosulfate hydrogen and decompose quickly. New product sometimes has mercaptan odor, slight moisture absorption.
The above information is edited by the chemicalbook of Wang Xiaodong.


1. It can be used for the production of catalysts, stabilizers, polymerization inhibitors, electroplating additives, photographic chemicals, pesticides, dyeing auxiliary and processing agents. It can be also used as polymer curing agents, crosslinking agents, rubber additives and pharmaceutical raw materials.
2. It can be also used as vulcanizing agent and crosslinking agent of polymer, rubber additives, pharmaceutical raw materials, etc.
3. It can be also used as analytical reagents.

Production method

Thioacetamide can be obtained by the reaction of acetonitrile with hydrogen sulfide, or acetamide with phosphorus pentasulfide.

Chemical Properties

White solid


Sulfide generation


Substitute for H2S in laboratory qualitative analyses.


ChEBI: A thiocarboxamide consiting of acetamide having the oxygen replaced by sulfur.

General Description

White crystals with a mercaptan odor.

Air & Water Reactions

Slightly water soluble.

Reactivity Profile

Thioacetamide reacts with aqueous acid to generate hydrogen sulfide. Forms addition compounds and sulfides with salts of heavy metals. Hydrolyzed by acids or bases .


Toxic by ingestion and inhalation, a possible carcinogen.

Fire Hazard

Flash point data on Thioacetamide are not available; Thioacetamide is probably combustible.

Purification Methods

Crystallise the amide from absolute diethyl ether or *benzene. Dry it at 70o in a vacuum and store it over P2O5 at 0o under nitrogen. (It develops an obnoxious odour on storage, and absorption at 269nm decreases, hence it should be freshly recrystallised before use). [Beilstein 2 IV 565.]
