Өнімнің шолуы

2-Bromoethanol (also known as Ethylene Bromohydrin or Bromoethanol),, CAS No.: 540-51-2 , with the chemical formula C₂H₅BrO and a molecular weight of 124.96 g/mol. It is a colorless to pale yellow or dark brown hygroscopic liquid with a sweet, burning taste and relatively stable chemical properties, though it is toxic. This compound belongs to the class of halo alcohols and is primarily used in organic synthesis and industrial processes.

Қасиеттер

2-Bromoethanol exhibits the following key physical and chemical properties:

  • Физикалық күй: Сұйық (бөлме температурасында).
  • Сыртқы түрі: Colorless to pale yellow or dark brown liquid.
  • Odor/Taste: Mild odor; sweet, burning taste.
  • Еру нүктесі: Not widely reported (typically low, around -50 °C based on similar compounds).
  • Қайнау нүктесі: Approximately 150 °C (decomposes partially).
  • Қысымдылық: 1.59–1.60 g/mL (at 20 °C).
  • Ерігіштік: Miscible with water (forms an azeotrope); soluble in organic solvents like ethanol and ether.
  • Тұрақтылық: Relatively stable but hygroscopic; incompatible with strong oxidants, acids, and bases; may decompose upon heating.
  • Токсикалықтық: Toxic by ingestion, inhalation, and skin absorption; causes irritation to skin, eyes, and respiratory tract; classified as a hazardous substance (UN 1566, corrosive and toxic).
