4-(BROMOMETHYL)-TETRAHYDRO-2H-PYRAN - Introduction
4-Bromomethyltetrahydropyran (English name: 4-bromomethyltetrahydropyran) is an organic compound with the chemical formula C5H9BrO. The following is a description of its nature, use, preparation and safety information:
Properties: 4-Bromomethyltetrahydropyran is a colorless liquid with a pungent odor. It can be dissolved in many organic solvents such as ethanol, diethyl ether and dimethylformamide. It has a high boiling point and flash point, and can form a flammable and explosive mixture with air.
Purpose: 4-Bromomethyltetrahydropyran is often used as an important intermediate in organic synthesis. It can be used to prepare other compounds such as ketones, carboxylic acids, ethanediimides, etc.
preparation method: 4-bromomethyltetrahydropyran can be obtained by treating 2-oxo-4-bromobutane (methylbenzyl lithium bromide) with oxygen alcohol or alkali. It is necessary to pay attention to safety, reasonable operating conditions and control temperature during preparation.
Safety Information: 4-Bromomethyltetrahydropyran is irritating and harmful to the eyes, skin and respiratory system. Wear protective glasses, protective gloves and protective masks during use. Avoid contact with strong oxidants, away from fire and high temperature. Pay attention to ventilation conditions during storage and handling to prevent the accumulation of vapors. In case of accidental contact, rinse with plenty of water in time and seek the help of a doctor.
