D-Tartaric acid, white crystals,99.5%,D-(-)-tartaric acid is widely used  as an acidizing agent for beverages and other foods, and this use is similar to citric acid. Tartaric acid can be used as an acid dye mordant when it is combined with tannin. It is also used for some development and fixing operations in the photographic industry. Its iron salts are photosensitive and therefore they can be used to make blueprints. Tartaric acid could complex with a variety of metal ions, and it could be used for cleaning agent and polishing agent of metal surface. Potassium tartrate (Rochelle salt) can be used to prepare Fehling reagent, and it is also used as as laxatives and diuretics in medicine. In addition, it is also used as an intermediate of quinophan. The crystal has piezoelectric properties, so it could be used for the electronics industry. It is used as a chromatographic reagent and masking agent. It is used as resolving agent of medicine and as biochemical reagent. This product is widely used in food industry, such as beer foaming agent, food sour agent, flavoring agent. And it is also used for refreshing drinks, candy, fruit juice, sauce, cold dishes and baking powder. This product is in line with the Japanese food additives certificate. It is used as chiral source and resolving agent for chiral synthesis.
