13979-81-2 - Introduction
3,5-dibromo-4-methylphenol is an organic compound with the formula C7H6Br2O. The following is a detailed description of its nature, use, preparation and safety information:
Nature:
-Appearance: 3,5-dibromo-4-methylphenol is a white to yellowish crystalline solid.
-Solubility: It can be dissolved in organic solvents, such as alcohol, ether, acetate, etc., but the solubility in water is low.
Use:
-Chemical reagents: 3,5-dibromo-4-methylphenol is commonly used as a reagent in organic synthesis for the synthesis of other compounds, such as drugs, dyes, polymer materials, etc.
-Flame retardant: In some plastic and rubber products, it can be used as a flame retardant to improve the flame retardant properties of the material.
Preparation Method:
3,5-Dibromo-4-methylphenol is usually synthesized starting from p-methylphenol:
1. First, p-methyl phenol reacts with bromine water to generate p-bromomethyl phenol.
2. Then, p-bromomethyl phenol reacts with an electrophilic substituent (such as cuprous bromide) to replace the hydrogen atom to form 3,5-dibromo-4-methylphenol.
Safety Information:
3,5-dibromo-4-methylphenol is relatively safe under normal circumstances, and it is less harmful to the human body and the environment under the condition of correct use and storage. However, as an organic compound, it may cause irritation and corrosion to the skin, eyes and respiratory tract, so appropriate protective measures should be taken when using it, such as wearing gloves, goggles and masks. In the treatment and disposal of waste, should comply with the relevant safety procedures, and the correct disposal of waste to avoid pollution to the environment. Always follow laboratory or relevant workplace safety guidelines when using or contacting this compound.
