Thioglycolic acid, usually as its dianion, forms complexes with metal ions. Such complexes have been used for the detection of iron, molybdenum, silver, and tin. Thioglycolic acid reacts with diethyl acetylmalonate to form acetylmercaptoacetic acid and diethyl malonate, the reducing agent in the conversion of Fe (III) to Fe (II).
Chemical depilatory. A chemical depilatory is a cosmetic preparation used to remove hair from the skin. Common active ingredients are salts of thioglycolic acid and thiolactic acids. These compounds break the disulfide bonds in keratin and also hydrolyze the hair so that it is easily removed. Formerly, sulfides such as strontium sulfide were ...
Ammonium thioglycolate. [O-]C (=O)CS. [NH4+] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Ammonium thioglycolate, also known as perm salt, is the salt of thioglycolic acid and ammonia. It has the formula HSCH 2 CO 2 NH 4 and has use in perming hair.
The chemical solution used in the perming process is determined by the client's hair type and the pH of the solution. Classic alkaline perms are used for stronger, coarser hair. They work at room temperature and usually contain ammonium thioglycolate in the pH range of 9-10. Acid perms are used on more delicate or thinner hair.
Halide displacement, using the suitable organic halide and sodium hydrogen sulfide has also been used. [23] Another method entails the alkylation of sodium hydrosulfide. RX + NaSH → RSH + NaX (X = Cl, Br, I) This method is used for the production of thioglycolic acid from chloroacetic acid.
Displacement of chloride by sulfide gives thioglycolic acid, which is used as a stabilizer in PVC and a component in some cosmetics. [2] Illustrative of its usefulness in organic chemistry is the O-alkylation of salicylaldehyde with chloroacetic acid, followed by decarboxylation of the resulting ether, producing benzofuran.

Thiolactic acid is the organosulfur compound with the formula C H 3CH (S H)C O 2H. The molecule contains both carboxyl and thiol functional groups, −C (=O)−OH and −SH respectively. It is structurally related to lactic acid by the interchange of −SH for −OH. It is a colorless oil. Thiolactic acid was once widely used in hair permanent ...
The Fiesselmann thiophene synthesis is a name reaction in organic chemistry that allows for the generation of 3-hydroxy-2-thiophenecarboxylic acid derivatives from α,β-acetylenic esters with thioglycolic acid and its derivatives under the presence of a base. The reaction was developed by Hans Fiesselmann in the 1950s. [1][2][3][4][5][6]
