Product Overview
1-Bromopropane (also known as n-Propyl Bromide) CAS No.: 106-94-5 is , with the chemical formula C₃H₇Br and a molecular weight of 122.99 g/mol. It is a colorless to pale yellow liquid with a characteristic hydrocarbon odor. This compound belongs to the class of alkyl halides and is primarily used as a solvent and intermediate in chemical synthesis, though its use is increasingly restricted due to environmental and health concerns.
Properties
1-Bromopropane exhibits the following key physical and chemical properties:
- Physical State: Liquid (at room temperature).
- Appearance: Colorless to pale yellow liquid.
- Odor: Strong, hydrocarbon-like odor.
- Melting Point: -110 °C.
- Boiling Point: 71 °C.
- Density: 1.35 g/mL (at 20 °C).
- Solubility: Slightly soluble in water (0.24 g/100 mL at 20 °C); miscible with organic solvents like ethanol, ether, and chloroform.
- Stability: Flammable; forms explosive mixtures with air; incompatible with strong oxidants, strong bases, and certain metals.
- Toxicity: Toxic by inhalation, ingestion, and skin contact; causes irritation to skin, eyes, and respiratory tract; potential reproductive and neurological toxicity (GHS: Acute Tox. 4, Repr. 2, STOT RE 2); classified as a hazardous substance (UN 2344).
Applications
The primary applications of 1-bromopropane include:
- Solvent: Widely used as a solvent in industrial cleaning, degreasing, and electronics manufacturing (e.g., for cleaning circuit boards), though its use is declining due to regulatory restrictions.
- Organic Synthesis Intermediate: Used in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds, such as propyl derivatives.
- Other: Employed in the production of adhesives, aerosols, and as a reagent in laboratory settings for alkylation reactions.
Classification
The following table outlines the classification of 1-bromopropane based on chemical properties, uses, and regulations:
| Classification Type | Specific Category | Description |
|---|---|---|
| Chemical Class | Alkyl Halide (Bromoalkane) | A primary brominated alkane, reactive in nucleophilic substitution reactions (e.g., SN2). |
| Usage Class | Industrial Solvent/Synthesis Reagent | Primarily used for cleaning and degreasing; also an intermediate in chemical synthesis. |
| Hazard Class | Flammable Liquid (UN 2344); Toxic | Flammable (flash point -10 °C); toxic with reproductive and neurological risks (GHS: Flam. Liq. 2, Acute Tox. 4, Repr. 2). |
| Regulatory Class | Regulated Chemical (TSCA, EPA) | Restricted under US EPA (SNUR) and other regulations due to environmental persistence and toxicity; classified as a volatile organic compound (VOC). |
Note: Due to its toxicity and environmental impact, 1-bromopropane is subject to strict regulations in many regions (e.g., EU, US). Users should consult local regulations and consider safer alternatives for solvent applications.
