C16H14O6•3H2O=356.36

Grade: High Purity Grade

Content: ≥ 95%

Melting point: 140 ºC

Solubility: Good in alcohol

Moisture content: ≤ 6%

Em (550nm, 0.1M NaOH):>14700

Appearance: White to light yellow crystals, turning red when exposed. Soluble in hot water and hot ethanol, with a solubility of about 1mg/ml. Also soluble in hydroxide alkali, borax solution, and glycerol, slightly soluble in cold water and ether. The color of the solution darkens during storage, with a melting point of 100-120 ºC (140 ºC). It is stimulating. Hematoxylin is a pigment extracted from the dried branches of South American sumac (a tropical leguminous plant) using ether, and is one of the most commonly used dyes. Hematoxylin cannot be directly stained and must be exposed to ventilated areas to turn it into oxidized hematoxylin (also known as hematoxylin) before use, which is called "maturation". The maturation process of hematoxylin takes a longer time, and the longer it is prepared, the stronger the dyeing power. The dyed material must be treated with a metal salt as a solvent before it can have coloring power. So when preparing hematoxylin dyes, a mordant should be used. Commonly used mordants include aluminum sulfate, potassium alum, and iron alum. Hematoxylin is an excellent material for staining the nucleus, as it can differentiate different structures in cells into various colors. The color of the tissue during differentiation varies depending on the treatment. After differentiation with an acidic solution (such as h-y-d-r-o-c-h-l-o-r-i-c a-c-i-d alcohol), it turns red, but after washing with water, it still returns to cyan blue. After differentiation with an alkaline solution (such as a-m-m-o-n-i-a), it turns blue, and after washing with water, it turns blue black. When exposed to light, it turns red. In aqueous solutions, especially in alkaline solutions, it is easily oxidized by air to reddish brown oxidized hematoxylin.

Purpose: Biochemical research. Staining agents for nuclei and chromatin. Blue or black can be obtained by using different mordants. Qualitative testing of copper (II), iron (III), molybdate, bismuth (III), and tin (IV); Photometric determination of vanadium, aluminum, tin (IV), f-l-u-o-r-i-n-e, niobium, tantalum, etc; Ink manufacturing; Acid base indicator. PH 5.0 (yellow) to 6.0 (purple), 0.0 (pink) to 1.0 (green).

Save: RT, avoid light
