What are the upstream raw materials for thioglycolic acid? What do the downstream products contain?

Thioglycolic acid(TGA) is a kind of organic acid containing thiol(-SH) functional group, which is broadly applied in chemical sector, medicine, agriculture and other fields. And In the field of raw materials to chemical production, the upstream and downstream related items of thioglycolic acid mainly include the following categories:



1. Upstream items(1) acetaldehyde: acetaldehyde reacts with hydrocyanic acid to generate acetaldehyde nitrile, and then hydrolyzed to obtain thioglycolic acid. Generally speaking(2) Sulfuric acid: Sulfuric acid is applied as a catalyst in the manufacturing process of thioglycolic acid to promote the interaction. And(3) hydrocyanic acid: hydrocyanic acid reacts with acetaldehyde to form acetaldehyde nitrile, which is hydrolyzed to obtain thioglycolic acid. Furthermore

2. Downstream items(1) Ethyl mercaptoacetate: The esterification of mercaptoacetic acid with ethanol produces ethyl mercaptoacetate, which is an crucial medical intermediate. Pretty interesting, huh?. But(2)N-phenylglycine: Mercaptoacetic acid reacts with aniline to create N-phenylglycine, which is a pesticide intermediate.(3) dithiodipropionic acid: thioglycolic acid reacts with sulfuric acid to generate dithiodipropionic acid, which is a rubber additive.(4) isooctyl thioglycolate: thioglycolic acid reacts with isooctyl alcohol to generate isooctyl thioglycolate, which is a plastic stabilizer. From what I've seen, Moreover The above is only a part of the upstream and downstream related items of thioglycolic acid. In fact, thioglycolic acid has a wide range of applications in the chemical sector, and there are many upstream and downstream items. The specific items are related to the manufacturing process, raw material sources, market demand and other factors.
