Product Application of Glyoxal CAS#107-22-2
Glyoxal is primarily used in the textile industry as a fiber treatment agent to enhance the shrinkage and wrinkle resistance of materials like cotton and nylon. It acts as a durable pressing agent, with Japan accounting for 80% of its total consumption for this purpose. Additionally, glyoxal serves as an insoluble adhesive for substances such as gelatin, animal glue, cheese, polyvinyl alcohol, and starch.
In the leather industry, glyoxal is applied, and it is also used in the production of waterproof matches. Glyoxal is a key raw material in organic synthesis processes, such as reacting with acetaldehyde, urea, and formaldehyde to create 2D-resin, which is used in fabric finishing.
Glyoxal can also react with formaldehyde and ammonium sulfate to form imidazole, which is then used to synthesize antifungal drugs like clotrimazole and miconazole. It is an important intermediate in the production of pyrazinamide, an anti-tuberculosis drug, and hydroxyphenylacetic acid, an intermediate for antibiotics and vitamin A products. Furthermore, glyoxal is used in the synthesis of berberine hydrochloride, sulfamethoxypyrazine (a sulfonamide drug), insecticides, deodorants, corpse preservatives, and sand mold curing agents.
