3378-82-3 - Introduction
1-Bromo-2-naphthaldehyde is an organic compound with the molecular formula C11H7BrO. The following is a detailed description of its nature, use, formulation and safety information:
Nature:
1-Bromo-2-naphthaldehyde is a colorless or pale yellow solid with a distinctive fragrance. It forms a clear solution when dissolved in some organic solvents such as ethanol and ether. This compound is stable in air, but it is sensitive to light and should be avoided from prolonged exposure to light.
Use:
The 1-Bromo-2-naphthaldehyde has some important uses. First, it is widely used as a starting material and intermediate in organic synthesis. It can be used in the preparation of other compounds such as fluorescent dyes, drugs and pesticides. In addition, it can also be used to prepare high molecular materials, such as polymers and resins.
Method:
The preparation method of 1-Bromo-2-naphthaldehyde can be obtained by bromination reaction of 2-naphthoic acid. First, 2-naphthoic acid is reacted with brominated sulfoxide (or brominated sulfoxide and bromine) to produce 1-bromo-2-naphthoic acid. 1-Bromo-2-naphthoic acid is then subjected to a hydroformylation reaction with an acid catalyst such as sulfuric acid to give 1-Bromo-2-naphthaldehyde.
Safety Information:
The safety of 1-Bromo-2-naphthaldehyde has not been fully evaluated, so general laboratory safety procedures should be followed when using it. It may cause irritation to the eyes, skin and respiratory tract, so contact with these areas should be avoided. In addition, work in a well-ventilated area and use personal protective equipment such as gloves and goggles. If ingested or inhaled, seek medical help immediately.
