Ethyl pyruvate (English ethyl pyruvate), the molecular formula is CH3COCOOC2H5, also known as ethyl 2-oxopropionate, a colorless transparent liquid at room temperature, with a fresh, sweet floral and fruity aroma, can be used for apples, citrus, chocolate, etc. In the preparation of fragrance. It is an extremely important organic synthetic intermediate. It is used in medicine (synthesis of thiimi drugs), pesticides (herbicides produced by DuPont, thiamine fungicides), foods (can be used as preservatives, preservatives, etc.), cosmetics And other industries have a wide range of uses.

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 an efficient active ingredient, which can effectively remove ammonia and methyl mercaptan in the air, and the smell is fresh and natural. Ethyl pyruvate is superior in the formation of heterocyclic compounds, and is a raw material and intermediate that is difficult to replace in the synthesis of pesticides. It is widely used in the synthesis of fungicides and herbicides, and oxazolone derivatives synthesized from ethyl pyruvate It is also a good fungicide, which can effectively inhibit and kill fungi at a concentration of 5.0 × 10-4.

Pyruvate is the main raw material for the production of tryptophan, phenylalanine, protein sugar, and vitamin B. It is the raw material for biosynthesis of L-dopa (dopa is used to treat Parkinson's syndrome). It is a starting agent for ethylene polymers. It is also the raw material for the preparation of grain protectants. A high-efficiency herbicide is synthesized from pyruvic acid. The herbicide has excellent selectivity, has good removal effect on weeds such as sedge and bristlegrass, and is safe for crops. As a feed and food additive, it has a good antiseptic and fresh-keeping function, and a small amount of it is used in the storage of feed and fruit wine in China. Ethyl pyruvate itself has a special fragrance and can be used in flavors and fragrances. It is also an important raw material for synthetic resins and plastics. Pyruvate products can also be used as special solvents in electronic materials, and the demand for foreign applications in this area has increased rapidly.
