For chemists and procurement specialists in the chemical industry, a thorough understanding of a compound's properties is fundamental to its effective application and safe handling. 3-Bromopropionitrile (CAS 2417-90-5) is a versatile organic intermediate whose utility is directly linked to its distinct chemical characteristics. As a key supplier of this compound, we aim to provide clarity on these properties, ensuring our clients can make informed purchasing decisions.

Physical and Chemical Profile of 3-Bromopropionitrile

3-Bromopropionitrile (Molecular Formula: C3H4BrN, Molecular Weight: 133.97 g/mol) is a clear, colorless liquid. Its physical state at room temperature is a key indicator of its handling requirements. The specific gravity and boiling point are critical for distillation, purification, and reaction condition optimization.

  • Boiling Point: The reported boiling point is 76-78 °C at 10 mm Hg. This relatively low boiling point under reduced pressure suggests it can be purified by vacuum distillation, a common technique for sensitive organic compounds.
  • Density: With a density of 1.615 g/mL at 25°C, it is denser than water, which can be relevant in liquid-liquid extraction and phase separation processes.
  • Refractive Index: The refractive index (n20/D) is around 1.4787, a useful parameter for quick identity checks and purity assessment.
  • Solubility: It is soluble in common organic solvents such as ethanol and ether, facilitating its use in various reaction media.

Reactivity and Stability

The reactivity of 3-Bromopropionitrile stems from the polarized C-Br bond, making the carbon atom susceptible to nucleophilic attack. This property is central to its role as an alkylating agent in organic synthesis. The nitrile group is also reactive and can undergo hydrolysis, reduction, or cycloaddition reactions. From a stability perspective, it requires storage below +30°C, as indicated by its storage temperature guidelines, to maintain its integrity over time.

Safety Considerations

As with many reactive chemicals, 3-Bromopropionitrile presents hazards. It is classified under hazard codes T, indicating toxicity. Risk statements like 23/24/25 (toxic by inhalation, in contact with skin, and if swallowed) and 36/37/38 (causes skin and eye irritation, and respiratory irritation) highlight the need for appropriate personal protective equipment (PPE) and handling procedures. Safety statements recommend using it in well-ventilated areas and wearing protective clothing. It is transported under UN 3276, Class 6.1, Packing Group III.
