Bromopropane
CAS NO.: 106-94-5
Content:99.00%
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 (REACH, TSCA, EPA) | Restricted under EU REACH, 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. For further details on regulatory status, refer to specific regulatory websites like EPA or ECHA.
