Tartarate

a colourless odourless poisonous crystalline salt used as a mordant for textiles and leather, as an insecticide, and as an anthelmintic. Formula: K(SbO)C4H4O6 Also called tartar emetic

Chiral alcohol useful as a building block in the synthesis of enantiomerically pure pharmaceuticals, chiral auxiliaries and other optically active compounds.

Potassium tartrate, dipotassium tartrate or argol has formula K2C4H4O6. It is the potassium salt of tartaric acid. It is often confused with potassium bitartrate, also known as cream of tartar. As a food additive, it shares the E number E336 with potassium bitartrate.

Sodium tartrate (Na2C4H4O6) is used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings. As a food additive, Because its crystal structure captures a very precise amount of water, it is also a common primary standard for Karl Fischer titration, a common technique to assay water content.

It is prescribed to abort or prevent vascular headaches such as migraines.

Metoprolol (often misspelled or mispronounced as "metropolol") is a selective β1 receptor blocker used in treatment of several diseases of the cardiovascular system, especially hypertension. It is marketed under the brand name Lopressor by Novartis, and Toprol-XL (in the USA); Selokeen (in the Netherlands); as Minax by Alphapharm (in Australia), Metrol by Arrow Pharmaceuticals (in Australia), as Betaloc by AstraZeneca, as Neobloc by Unipharm (in Israel), Presolol by Hemofarm (in Serbia) and as Corvitol by Berlin-Chemie AG (in Germany).

Monosodium tartrate or sodium bitartrate is a sodium salt of tartaric acid. As a food additive it is used as an acidity regulator and is known by the E number E335

Potassium bitartrate, also known as potassium hydrogen tartrate, has formula kc4h5o6. It is a byproduct of winemaking. In cooking it is known as cream of tartar. It is the potassium acid salt of tartaric acid, a carboxylic acid.
