Product Application of Glyoxal CAS#107-22-2

Glyoxal is mainly used in the textile industry. As a fiber treatment agent, it can increase the shrinkage and wrinkle resistance of cotton, nylon and other fibers. It is a durable pressing finishing agent. In Japan, this use accounts for 80% of the total consumption of glyoxal. Acetaldehyde is an insoluble adhesive for gelatin, animal glue, cheese, polyvinyl alcohol and starch. Glyoxal is also used in the leather industry and for making waterproof matches. Glyoxal is a raw material for organic synthesis. Acetaldehyde, urea and formaldehyde are heated and condensed in the presence of sodium carbonate to obtain 2D-resin, which is used as a fabric finishing agent;

Glyoxal reacts with formaldehyde and ammonium sulfate to cyclize imidazole, and then synthesizes imidazole antifungal drugs such as clotrimazole and miconazole; glyoxal cyclizes with o-phenylenediamine to obtain benzopyrazine: it is an intermediate of the anti-tuberculosis drug pyrazinamide. Hydroxyphenylacetic acid produced from glyoxal has been industrially produced in Japan and used as an intermediate for antibiotics and vitamin A series products. Glyoxal is also used in the synthesis of berberine hydrochloride and sulfonamide drugs sulfamethoxypyrazine. It is also used in insecticides, deodorants, corpse preservatives, and sand mold curing agents.
