848358-81-6 - Introduction
It is an organic compound with the chemical formula of C7H8BrNO.
Nature:
-Appearance: Often white to light yellow crystalline, solid.
-Melting point: The melting point is about 140-142 degrees Celsius.
-Solubility: Slightly soluble in water, soluble in organic solvents such as alcohols, ethers and ketones.
Use:
-Biochemistry: Commonly used as substrates and inhibitors of certain enzymes.
-Drugs: can be used as intermediates in the synthesis of antibiotics, anti-tumor drugs and other drugs.
-Cosmetics: Commonly used in certain skin whitening and anti-aging products.
Preparation Method:
It can be prepared by the following synthetic route:
generally, 4-bromo -2-methyl phenol is obtained by bromination reaction with bromine-p-methyl phenol first, and then electrophilic substitution reaction with sodium nitrite and hydrochloric acid is performed to obtain 4-bromo -2-nitrophenol. Finally, the target product is obtained by reduction with sodium bisulfite.
Safety Information:
-specific toxicity and danger of the study results are not clear, but as a chemical, should be used with caution.
-Avoid inhaling, swallowing or touching the substance during operation. In case of accidental contact, please rinse with plenty of water in time and consult a doctor.
-The substance needs to be stored in a dry, well-ventilated place, away from fire and combustibles.
