What is β-Bromophenylethane CAS 103-63-9?
Molecular formula: C₈H₉Br, molecular weight 185.06 g/mol.
Appearance: Colorless to pale yellow transparent liquid with a characteristic bromid-like odor.
Key physical properties:
Melting point: -56°C
Boiling point: 220-221°C (normal pressure), 92°C (1.46 kPa)
Density: 1.355-1.366 g/mL (25°C)
Flash point: 89-96°C (Flammable liquid, fire prevention required)
Refractive index: n²⁰/D = 1.556-1.557
Solubility: Insoluble in water (solubility 0.039g /L), readily soluble in organic solvents such as ether, benzene, and ethanol.
Stability: Stable at room temperature, but reacts vigorously with strong oxidants; Long-term storage should be kept away from light and at low temperatures (2-8°C).
β -bromobenzene ethane, as a multifunctional organic intermediate, is irreplaceable in the fields of pharmaceuticals (Prostrum), flame-retardant materials (polybrominated styrene), and industrial auxiliaries.
