Propanoic acid, 2-oxo-, ethyl ester

Ethyl pyruvate, molecular formula is CH3COCOOC2H5, also called ethyl 2-oxo propionic acid, it is colorless and transparent liquid at room temperature, with fresh and sweet floral aroma, which can be used in the preparation of essence such as apple, orange and chocolate.It is an extremely important intermediate in organic synthesis and has a wide range of USES in medicine (synthetic thiamethoxam), pesticide (herbicide produced by dupont company, thiamethoxam fungicide), food (can be used as preservative, preservative, 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 air freshener as a highly effective active ingredient, which can effectively remove ammonia and methyl mercaptan in the air, and has a fresh and natural smell.Ethyl pyruvate has superior performance in the formation of heterocyclic compounds, and 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 good fungicides, which can effectively inhibit and kill fungi at the concentration of 5.0 10-4.

Pyruvate is the main raw material for the production of tryptophan, phenylalanine, proteoglycan and B vitamins. It is the raw material for the biosynthesis of l-dopamine (dopamine is used to treat Parkinson's disease), the initiator of ethylene polymer, and the raw material for the preparation of cereal protective agents.A highly effective herbicide was synthesized from pyruvic acid. The herbicide had good selectivity, good weed removal effect on sedge, cygtail and other weeds, and very safe for crops.As feed and food additive, it has good function of preservation and preservation.Ethyl pyruvate itself has a special fragrance, can be used in flavor, spices, but also synthetic resin and plastic important raw materials.Pyruvate ester products can also be used as special solvents for electronic materials, in this regard the application of foreign demand increased rapidly.
