[1]) is a water-soluble sodium salt of Alizarin sulfonic acid with a chemical formula of C 14 H 7 NaO 7 S. [2] [1] Alizarin Red S was discovered by Graebe and Liebermann in 1871. [2] In the field of histology alizarin Red S is used to stain calcium deposits in tissues, [3] [4] and in geology to stain and differentiate carbonate minerals. [3]
A diaphonized mirror dory.The bones are dyed red and the cartilage is dyed blue. Diaphonized veiled chameleon. Field Museum of Natural History, Chicago.. Diaphonization (or diaphonisation), also known as clearing and staining, is a staining technique used on animal specimens that first renders the body of the animal transparent by bathing it in trypsin, and then stains the bones and cartilage ...
Thus, both pure calcium and calcium in bones and other tissues can be stained. These alizarin-stained elements can be better visualized under fluorescent lights, excited by 440–460 nm. [18] The process of staining calcium with alizarin works best when conducted in acidic solution (in many labs, it works better in pH 4.1 to 4.3). [19]

It fades faster than alizarin on exposure to sunlight. [2] A study published in Nature journal Scientific Reports suggests that the purpurin could replace cobalt in lithium-ion batteries. [8] Eliminating cobalt would mean eliminating a hazardous material, allow batteries to be produced at room temperature, and lower the cost of recycling batteries.

The name "anthraquinone" was first used by German chemists Carl Graebe and Carl Theodore Liebermann in a 1868 publication describing the chemical synthesis of the red dye alizarin from anthracene, a component of coal tar. This discovery led to the industrial production of alizarin and the impetus for further research on anthraquinone chemistry. [1]
Hydrated sections of formaldehyde-fixed tissue are usually pre-treated with Bouin solution to obtain correct results in the trichrome stains for contrasting colours in collagenous and cytoplasmic (muscle) fibres. The trichrome methods were devised for tissues fixed in acidic mixtures containing mercuric chloride, which are now used only on a ...
