HScode：

2903799090

Characteristics

PSA：

XLogP3：

1.41

Appearance：

Bromochloromethane appears as a clear colorless liquid with a sweet chloroform-like odor. Denser than water (density 1.991 g / cm3) and insoluble in water. Hence sinks in water. Boiling point 68°C. Vapors may cause illness if inhaled. Nonflammable. When exposed to high temperatures may emit toxic fumes. Used as a fire extinguishing agent.

-87.9 °C

Boiling Point：

68.0 °C

Flash Point：

11 °C

Refractive Index：

1.466

Water Solubility：

H2O: 9 g/L (20 ºC)

2-8°C

Vapor Pressure：

117 mm Hg ( 20 °C)

Vapor Density：

4.5 (vs air)

Toxicity：

Oral-Rat LD50: 5000 mg/kg; Oral-Mouse LD50: 4300 mg/kg

Flammability characteristics：

It is non-combustible by itself; it decomposes the halide toxic vapor when heated

Odor：

2100 mg/cu m (odor threshold low); 2100 mg/cu m (odor threshold high) sweet.
