57409-51-5 - Introduction

Methyl 2, is an organic compound with the chemical formula C10H8O4S. The following is a description of its nature, use, preparation and safety information:

Nature:
-Appearance: methyl 2, is a solid, commonly white to light yellow crystals.
-Solubility: It is soluble in organic solvents such as ethanol, dichloromethane and tetrahydrofuran.

Use:
- methyl 2 can be used as an intermediate for the synthesis of complex organic compounds. It is often used in organic synthesis to prepare other organic pesticides, antibiotics, pharmaceuticals and functional materials.

Preparation Method:
- methyl 2, can be prepared by the following reaction:
1. First, 2,4-dioxo-4-thiophen-2-yl methanol is reacted with sodium hydroxide to generate the corresponding 2,4-dioxo-4-thiophen-2-yl acid.
2. Then, 2,4-dioxo-4-thiophen-2-yl acid and the corresponding alcohol (such as methanol) are esterified to obtain 2,4-dioxo-4-thiophen-2-yl acid ester.
3. Finally, the 2,4-dioxo-4-thiophen-2-yl ester is deprotected or oxidized to obtain the oxyalcohol ester compound-methyl 2, phenyl.

Safety Information:
- methyl 2, relatively stable under conventional experimental conditions, but still avoid contact with strong oxidants or strong acids.
-Take appropriate precautions during handling and handling, such as wearing chemical protective gloves and goggles.
-When conducting experiments, operate in a well-ventilated environment to avoid direct inhalation of dust or vapor.
-When storing, the compound should be stored in a sealed container, away from fire and flammable substances, and away from direct sunlight.
-When in contact with skin or eyes, rinse immediately with plenty of water and seek medical help.

Please note that when using or handling chemicals, relevant safety regulations should be observed and proper laboratory operations should be carried out.
