9,10-Anthracenedione, 1,3-dihydroxy-8-methoxy-6-methyl- - Introduction
1-Methyl Emodin(1-Methyl Emodin) is a chemical substance that contains Emodin (also known as rutin) and a Methyl ether group in its chemical structure. The following is an introduction to the nature, use, formulation and safety information of 1-Methyl Emodin:
Nature:
- 1-Methyl Emodin is an orange-yellow crystalline or crystalline powder.
-It is almost insoluble in water at room temperature, but soluble in organic solvents such as ethanol, dichloromethane and dimethyl sulfoxide.
-It has a certain degree of stability and is not easy to decompose under light.
Use:
- 1-Methyl Emodin is commonly used as a natural pigment additive in food, cosmetics and pharmaceuticals.
-It can be used as a pH indicator or fluorescent dye, and has certain applications in scientific research experiments.
Method:
- 1-Methyl Emodin can be prepared by chemical reaction of Emodin. The common method is to react Emodin with methanol under acidic conditions, the Methyl group of methanol is substituted for one hydrogen atom of Emodin to obtain 1-Methyl Emodin.
Safety Information:
- 1-Methyl Emodin has low toxicity and will not cause obvious harm to the human body under normal circumstances.
-However, if it comes into direct contact with 1-Methyl Emodin, it may cause eye and skin irritation, so pay attention to personal protective measures when using it.
-When storing and handling 1-Methyl Emodin, care should be taken to avoid fire and avoid contact with oxidants, strong acids and other substances.
