China [CN]

Basic Information

Chinese Name: 2-Bromo-5-ethylthiophene

English Name: 2-Bromo-5-ethylthiophene

Molecular Formula: C₆H₇BrS

Molecular Weight: 191.09

CAS Number: 1455-20-5

Physical and Chemical Properties

Appearance: Typically a colorless to pale yellow liquid, relatively stable, but should be kept away from strong light and high temperatures.

Density: Approximately 1.49 g/cm³ (at 25°C, estimated or experimental range).

Boiling Point: Approximately 160-165°C (at atmospheric pressure, the specific value may vary slightly depending on purity); the boiling point decreases under reduced pressure, e.g., to 60-62°C/10 mmHg (estimated based on data from analogs).

Refractive Index: n₂O/D approximately 1.55-1.56 (a characteristic value reflecting the optical properties of the molecule).

Solubility: Freely soluble in organic solvents (such as ether, chloroform, and toluene), poorly soluble in water.
