2-Bromo-5-chlorotoluene

  Product Detail  

• Appearance & Odor : Colorless to pale yellow transparent liquid; mild aromatic odor (typical of alkyl-substituted halobenzenes); chemically stable under normal temperature and pressure. ​

• Melting Point : -10 °C to -8 °C (lit., liquid at room temperature) ​

• Boiling Point : 220-222 °C (at atmospheric pressure); 105-107 °C at 15 mmHg (vacuum distillation condition); flash point 92 °C (closed cup) ​

• Density : 1.562 g/cm³ (20 °C, experimental value) ​

• Refractive Index : n²⁰/D 1.5580-1.5600 (20 °C) ​

• Solubility : Insoluble in water (solubility 1 g/L at 25 °C); freely soluble in organic solvents ​

• Purity Specification : Industrial grade ≥ 98.0% (GC), pharmaceutical intermediate grade ≥ 99.0% (HPLC); total impurities ≤ 2.0% (main impurities: isomeric bromochlorotoluenes, trace moisture, unreacted toluene derivatives). ​

• Reactivity : Stable under ambient conditions; incompatible with strong oxidizing agents and strong bases at elevated temperatures; undergoes typical aromatic substitution reactions (e.g., nitration, sulfonation, Suzuki coupling) due to the activating effect of the methyl group. ​
