Description

Tetrabromobisphenol A is a white to pale cream or pale yellow crystalline with a moderately high molecular weight, low water solubility, and moderately high lipophilicity (as indicated by log K
ow
). Only about 4% of the particles are <15 μm in diameter, and thus, little (<4%) is expected to be respirable (<10 μm in diameter) and absorbed from the lung after inhalation exposure.

Tetrabromobisphenol A (TBBPA) is a brominated flame retardant used in a variety of reactive and
