About DL-Tartaric Acid E334-133-37-9
E334 is a white crystalline diprotic acids. E334 naturally in many plants, especially grapes, bananas, and tamarind, E334-133-37-9 is found in wine, one of the major organic acids. E334 is to add other foods sour, is used as an antioxidant. Tartrate is known as tartaric acid. E334 is a succinate-dihydroxy derivatives. E334 mainly for the manufacture of tartaric acid salts, such as antimony potassium tartrate, potassium sodium tartrate, etc. E334-133-37-9 in the beer industry as a foaming agent, food acidulant, flavoring agent. E334 acidity as citric acid 1.3 times, especially suitable for grape juice sour agent.

E334-133-37-9 with two symmetrical chiral carbon, with the three isomers. E334-133-37-9 is an antioxidant, has been applied in the food industry. Biochemical tests can be used as oxygen scavenger E334. Also known as 2,3 - dihydroxybenzoic acid. E334 mainly in the form of potassium in a variety of plants and fruits, is also a small amount of free states exist. E334 and citric acid is similar for the food industry, such as the manufacture of beverages. E334-133-37-9 and tannin combination can be used as a mordant acid dyes. E334-133-37-9 with a variety of metal ions, can be used for metal surface cleaning agents and polishing agents. Potassium sodium tartrate, also known as Rochelle salt can be prepared Fehling, medicine can be done on the laxatives and diuretics. Tartrate crystals have piezoelectric properties, can be used for the electronics industry. Antimony potassium tartrate to vomiting agents, also known as tartar emetic, E334-133-37-9 to treat schistosomiasis applications. E334 is the largest beverage additive purposes. Then the drug industry raw materials. In contemporary organic synthesis E334 is a very important chiral ligands and hand temper, E334 can be used to prepare many well-known chiral catalysts, as well as the chiral source to synthesize complex natural product molecules.
