141524-74-5 - Introduction
4-Bromo-1-methyl-1H-imidazole-5-carbaldehyde, also known as BMIF (blium), is an organic compound. The following is a detailed description of its nature, use, preparation and safety information:
Nature:
-Appearance: BMIF is a colorless solid, usually in the form of crystals.
-Solubility: Soluble in organic solvents (such as ethanol, dichloromethane, chloroform), slightly soluble in water.
-Melting point: about 96-98 degrees Celsius.
-Molecular formula: C5H5BrN2O.
Use:
- BMIF can be used as an intermediate in organic synthesis, and has important application value in the fields of drug synthesis, pesticide synthesis and dye synthesis.
-It can also be used as a reagent in organic synthesis to initiate or promote specific reactions.
Preparation Method:
The preparation method of BMIF generally involves the following steps:
1. Preliminary reaction: 2-bromotoluene reacts with hydrazine in a suitable organic solvent to generate N-(2-bromoethyl)hydrazinecarboxymide.
2. Further reaction: The N-(2-bromoethyl)hydrazinecarboxymide is converted into BMIF through a condensation reaction with 1-methylimidazole under alkaline conditions.
Safety Information:
- BMIF is a chemical, so proper laboratory safety measures need to be taken during handling and use, including wearing appropriate personal protective equipment (such as gloves and goggles).
-Avoid contact with oxidants and strong acids during storage and transportation to avoid dangerous reactions.
-During use, avoid inhalation, contact with skin and eyes, and avoid ingestion into the mouth.
-Any specific safety information on BMIF should be obtained from the relevant literature or from the chemical provider's safety data sheet prior to use.
