Haematoxylin

CAS: 517-28-2
Molecular Formula: C16H14O6
Molecular Weight: 302.28
Product description:One of the most commonly used dyes and dye is a kind of natural media. Used for silk, fur and leather dyeing and printing of cotton, available in different mordant blue or black. In aqueous solution, especially in alkali solution easy oxidation by air oxidation into red brown hematoxylin. Hematoxylin cannot direct dyeing, must be exposed to the ventilation place, make he oxidation hematoxylin (also called wood grain) to use, this is called "mature". Hematoxylin "mature" process takes longer, the longer after configuration, dyeing force is stronger. Dyed material must be through the metal salts as agent before tinting strength. So in the preparation of hematoxylin dye with a mordant.
