Fast Delivery 130-22-3 Mordant Red 3 Direct Manufacturer with best price
In 1869, German chemists Karl Grebe and Karl Rieberman extracted anthracene from coal tar, which was then oxidized to anthraquinone, and then alkali melted into alizarin red. In this way, alizarin red became the first artificially synthesized natural dye. Its advent brought a huge impact on traditional vegetable dyes, alizarin red, which can be produced on a large scale and is cheap, suddenly meets the growing commercial demand, making the demand for natural alizarin red plummet. At that time, large tracts of European madder fields in France could only be converted to other crops. Today, alizarin red is still used as a dye on fabrics, but under the influence of other artificial dyes, its prosperity is not as good as before. Alizarin red extracted from the roots of Rubiaceae in Europe was previously used as a food additive pigment, but it was banned by Japan, European and American countries because of the carcinogenic risk found in research. At present, the commercial alizarin red is mostly used to dye fabrics, and it is also made into "madder lake" painting pigments. Of course, if you are a biological Wang, you may be more familiar with the so-called "osteoblast alizarin red dyeing experiment".
