D-Tartaric acid CAS 147-71-7 Product details

Tartaric Acid, that is, 2,3-dihydroxysuccinic acid, has a molecular formula of C4H606 and a relative molecular weight of 150.09. It was first obtained from the dregs during the production of wine through various chemical treatments. There are two asymmetric carbon atoms in the tartaric acid molecule, so there are left-handed form (L-tartaric acid), right-handed form (D-tartaric acid), meso form (MESO-tartaric acid) and racemate (DL- tartaric acid) these four isomers. D(-)-tartaric acid, also known as (2S,3S)-2,3-dihydroxybutane-1,4-dicarboxylic acid, is the isomer of natural L(+)-tartaric acid and is extremely abundant in nature. Rarely exists. In the pharmaceutical industry, it is mainly used as a chiral source and resolving agent for chiral synthesis.

D-Tartaric acid CAS 147-71-7 Application/Use

D-Tartaric acid, also known as Dihydroxybutanedioic acid, is a naturally occurring organic acid that belongs to the category of tartaric acids. It is the enantiomer of L-tartaric acid.

D-Tartaric acid has several applications and uses across various industries. Some of its prominent applications include:

Food and Beverage Industry: D-Tartaric acid is commonly used as an acidulant and flavoring agent in food and beverage products. It is known for its sour taste and is used in the production of soft drinks, confectionery, jams, jellies, gelatin desserts, and fruit juices. It is also used as a buffering agent to control the pH of food products.

Pharmaceutical Industry: D-Tartaric acid finds applications in the pharmaceutical industry as an excipient in the formulation of drugs. It is used to adjust the pH of formulations and enhance the stability of certain medications. Additionally, it is used as a chiral resolving agent to separate enantiomers in pharmaceutical synthesis.

Wine Industry: D-Tartaric acid is an important component in winemaking. It is naturally present in grapes and is responsible for the acidity and tartness of wine. During the winemaking process, D-Tartaric acid is used for acidification, pH adjustment, and for controlling the precipitation of potassium bitartrate crystals, also known as wine diamonds.

Chemical Industry: D-Tartaric acid serves as a precursor for the synthesis of various chemicals. It is used in the production of tartaric acid derivatives, such as tartaric esters, which find applications in the manufacturing of polymers, resins, and coatings. D-Tartaric acid can also be used as a resolving agent to separate racemic mixtures into their individual enantiomers.

Cosmetics and Personal Care Products: D-Tartaric acid is utilized in the cosmetics and personal care industry for its pH-regulating properties. It is employed in skincare, hair care, and personal hygiene products to adjust the acidity and maintain stability.

It’s important to note that while D-Tartaric acid has various applications, it is crucial to follow appropriate guidelines and regulations for its safe and proper use in each specific industry or application.
