Ethyl pyruvate also known as ethyl 2-oxopropionate, is a colorless transparent liquid at room temperature, with fresh and sweet aroma of flowers and fruits, which can be used in the preparation of apple, citrus, chocolate and other essence. It is an extremely important organic synthetic intermediate, which is widely used in medicine (synthetic thiamides), pesticides (herbicides and thiamides produced by DuPont), food (used as preservatives, preservatives, etc.), cosmetics and other industries. Ethyl pyruvate has a good effect on inhibiting the formation of tyrosinase in the epidermis, so it can prevent the formation of epidermal melanin and whiten the skin. It can also be added to the air freshener as a highly effective active ingredient, which can effectively remove ammonia and methyl mercaptan in the air, and the smell is fresh and natural. Ethyl pyruvate has excellent performance in forming heterocyclic compounds. It is an irreplaceable raw material and intermediate in pesticide synthesis. It is widely used in the synthesis of fungicides and herbicides. Oxazolone derivatives synthesized from ethyl pyruvate are also a good fungicide × 10-4 can effectively inhibit and kill fungi. Pyruvate is the main raw material for the production of tryptophan, phenylalanine, protein sugar and vitamin B, the raw material for biosynthesis of L-dopa (dopa is used to treat Parkinson's disease), the initiator of ethylene polymer, and the raw material for the preparation of grain protectants. A highly effective herbicide was synthesized from pyruvic acid. The herbicide has good selectivity, good effect on weeds such as sedge and bristlegrass, and is very safe for crops. As feed and food additive, it has good antiseptic and fresh-keeping functions. At present, a small amount of it is used in the preservation of feed and fruit wine in China. Ethyl pyruvate has its own special flavor, which can be used in essence and perfumes. It is also an important raw material for synthetic resins and plastics. Acetone ester products can also be used as special solvents for electronic materials, and the application in this field has increased rapidly abroad.
