Beschreibung

Produktübersicht

1-Bromododecane (also known as n-Dodecyl Bromide or Dodecyl Bromide) with CAS No.: 143-15-7 , with the chemical formula C₁₂H₂₅Br and a molecular weight of 249.23 g/mol. It is a clear, colorless to light yellow liquid with a characteristic odor. This compound belongs to the class of alkyl halides and is primarily used in organic synthesis and industrial applications, though it is subject to environmental and safety regulations due to its irritant properties and potential hazards.

Eigenschaften

1-Bromododecane exhibits the following key physical and chemical properties:

  • Physischer Zustand: Flüssig (bei Raumtemperatur).
  • Erscheinungsbild: Klare farblose bis hellgelbe Flüssigkeit.
  • Geruch: Characteristic odor.
  • Schmelzpunkt: -9.5 °C.
  • Siedepunkt: 276 °C (or 134-135 °C at 6 mmHg).
  • Dichte: 1.038 g/mL at 25 °C.
  • Löslichkeit: Insoluble in water; miscible with organic solvents like ethanol and ether.
  • Stabilität: Stable under normal conditions but air sensitive; flammable with a flash point of 110-146 °C; incompatible with strong oxidants, bases, and metals; store under inert gas in a cool, dark place.
  • Toxizität: Moderately toxic; causes skin, eye, and respiratory irritation; may cause neurological disorders; signal word “Warning”.

Anwendungen

The primary applications of 1-bromododecane include:

  • Organisches Synthese-Zwischenprodukt: Used as a long-chain alkylating agent to introduce the dodecyl group in the production of pharmaceuticals, agrochemicals, surfactants, and other organic compounds; improves lipophilicity and hydrophobicity of molecules for biological applications; used in synthesis of disinfection drugs and antimicrobial nanocomposites.
