34189-75-8 - Introduction
Bromoethane-13C2 is a bromoethane containing the 13C isotope. Its chemical formula is CH3CH13CH2Br. The following is a description of the nature, use, manufacture and safety information of the Bromoethane-13C2:
Nature:
-Appearance: colorless liquid
-Density: approx. 1.56g/cm³
-Boiling point: about 38-39 ° C
-Melting Point: About -119-117 ° C
Use:
- Bromoethane-13C2 are often used as labeled compounds for isotope tracing experiments in research and analysis.
-It can also be used as a chemical reagent in organic synthesis.
Method:
The preparation process of Bromoethane-13C2 is usually obtained by iodide exchange reaction. First, ethyl bromide is reacted with silver isocyanate to obtain a diisocyanate. Subsequently, The diisocyanate is converted to the corresponding dicyano salt by an iodination reaction and finally by an exchange reaction with methyl chloride to form Bromoethane-13C2.
Safety Information:
- Bromoethane-13C2 is a flammable liquid and should be stored in a well-ventilated place, away from fire and heat sources.
-Wear appropriate protective gloves and goggles during use or storage.
-Contact with Bromoethane-13C2 may cause irritation to the skin, eyes and respiratory tract, so direct contact should be avoided.
-If inhaled or ingested by mistake, seek medical attention immediately.
