Beschreibung
Phenethylbromide is an analytical reference material that is structurally categorized as an organobromide. It is used in the synthesis of a variety of compounds, including fentanyl. Phenethylbromide is combined with 4-piperidinone to produce N-phenethyl-4-piperidone, which, as a precursor in the synthesis of fentanyl, is scheduled as a List I chemical in the United States. Phenethylbromide may be found as in impurity in samples of fentanyl produced using this pathway.Chemische Eigenschaften
colourless to yellow liquid. It is miscible with ether and benzene, but insoluble in water.Verwenden
(2-Bromoethyl)benzene is an important starting material for the production of various b-phenethyl derivatives, pharmaceuticals, fragrances, and other fine chemicals.Verwenden
(2-Bromoethyl)benzene is used in the preparation of phenelzine by reacting with hydrazine. It is also used as a starting material to prepare various beta-phenethyl derivatives, active pharmaceutical ingredients, and fragrances. It finds application as a flame retardant.synthetische
(2-Bromoethyl)benzene is synthesized by the reaction of phenethyl alcohol with hydrogen bromide.Reaction: The phenethyl alcohol was heated to 110°C, hydrogen bromide was slowly introduced, and the reaction was refluxed. The reaction was completed, cooled, washed with water, 10% sodium carbonate solution, and water in turn. After drying with anhydrous potassium carbonate, fractional distillation under reduced pressure was carried out to collect fractions at 97-99°C (2.0 kPa) with a yield of over 90%.
Sicherheit(Safety)
Store at 2-8° C in a tightly closed container in a dry, well-ventilated place. Containers that are opened must be carefully resealed and kept upright to prevent leakage. (2-Bromoethyl)benzene is incompatible with strong oxidizing agents. This chemical is harmful if swallowed and causes severe eye irritation.l?uterung methode
Wash the bromide with conc H2SO4, water, aqueous 10% Na2CO3 and water again, then dry it with CaCl2 and fractionally distil it just before use. [Beilstein 5 IV 907.]Einzelnachweise
