2-Bromoethanol, with the CAS number 540-51-2, is a colorless to light yellow liquid. It has a molecular formula of C₂H₅BrO and a molecular weight of approximately 124.96 g/mol. The boiling point of 2-Bromoethanol is around 149 - 150°C, and its density is about 1.76 g/cm³ at 25°C. This product is supplied by our factory at the best price in the market. It is commonly used in various chemical reactions due to the presence of the bromine and hydroxyl functional groups.
2-Bromoethanol has a wide range of uses in the chemical industry. Firstly, it serves as an important intermediate in organic synthesis. It can be used to introduce the 2-bromoethyl group into different molecules. For example, in the synthesis of pharmaceuticals, it can be used to modify the structure of drug candidates, potentially enhancing their biological activity.
Secondly, it is used in the production of specialty chemicals. Some flame retardants and plasticizers can be synthesized using 2-Bromoethanol as a starting material. Its unique chemical properties allow it to react with other compounds to form products with specific functions, such as improving the heat resistance and mechanical properties of plastics.
When using 2-Bromoethanol, it is crucial to follow safety protocols. Always wear appropriate personal protective equipment, including gloves, goggles, and a lab coat. Work in a well - ventilated area, preferably under a fume hood, as the vapors of 2-Bromoethanol can be harmful if inhaled.
For handling, use glass or stainless - steel containers as 2-Bromoethanol may react with some metals and plastics. When measuring the product, use accurate volumetric or gravimetric methods. In chemical reactions, add 2-Bromoethanol slowly to the reaction mixture to control the reaction rate, especially when it is an exothermic reaction.
Case 1: Pharmaceutical Synthesis
A pharmaceutical company was developing a new anti - inflammatory drug. They used 2-Bromoethanol to modify the structure of an existing compound. By reacting 2-Bromoethanol with the target molecule under specific reaction conditions (such as in the presence of a base and an appropriate solvent), they were able to introduce a 2 - bromoethyl group. This modification improved the solubility and bioavailability of the drug candidate, leading to better in - vivo performance in animal studies. The reaction yield was around 70%, and after purification steps, the final product met the required quality standards.
Case 2: Flame Retardant Production
A chemical manufacturing plant was producing a new type of flame retardant for plastics. They used 2-Bromoethanol as one of the key starting materials. By reacting it with a phosphorus - containing compound and a polymer matrix, they were able to incorporate the bromine and phosphorus elements into the plastic structure. The resulting plastic had significantly improved flame - retardant properties, passing the required flammability tests. The production process was optimized over time to increase the efficiency and reduce waste.
