What are the main uses of formic acid

What are the main uses of formic acid:
Formic acid is one of the basic organic chemical raw materials, widely used in pesticides, leather, dyes, medicine and rubber industries. Formic acid can be directly used in fabric processing, tanning leather, textile printing and dyeing and green feed storage, and can also be used as metal surface treatment agent, rubber auxiliary and industrial solvent. In organic synthesis, it is used to synthesize various formates, acridine dyes and formamide series of medical intermediates. The specific categories are as follows:
Pharmaceutical industry: Caffeine, aminopyrine, aminophylline, theobromine borneol, vitamin B1, metronidazole, mebendazole.

Pesticide industry: powder, triazolone, tricyclozole, triamidazole, triazophos, polybulozole, tenobulozole, insecticide, dicofol and so on.
Chemical industry: calcium formate, sodium formate, ammonium formate, potassium formate, ethyl formate, barium formate, dimethylformamide, formamide, rubber antioxidant, pentaerythritol, neopentanediol, epoxy soybean oil, epoxy octyl soybean oleate, valeryl chloride, paint remover, phenolic resin, pickling steel plate, etc.
Leather industry: tanning preparations, deashing agents and neutralizing agents for leather.
Rubber industry: natural rubber coagulants. Medical | education | network collection and collation
Other: can also manufacture dyeing mordant, fiber and paper dyeing agent, treatment agent, plasticizer, food preservation and animal feed additives.
A reducing agent. Determination of arsenic, bismuth, aluminum, copper, gold, indium, iron, lead, manganese, mercury, molybdenum, silver and zinc. Verification of cerium, rhenium and tungsten. Testing aromatic primary and secondary amines. Determination of relative molecular weight and crystallization solvent. Methoxy group was determined. Used as fixative in microscopic analysis. Make formates.
Formic acid and its aqueous solution can dissolve many metals, metal oxides, hydroxides and salts, and the resulting formate can be dissolved in water, so it can be used as a chemical cleaning agent. Formic acid does not contain chloride ions and can be used for cleaning equipment containing stainless steel materials.
