Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
EBTBP has negligible solubility in organic solvents and water (see sections on water solubility, octanol/water partition coefficient, solubility in organic solvents). Development of a specific analytical method has not been possible. EPIv4.0 estimates EBTBP's Koc is 5.47 E+4 L/kg (Molecular Connectivity Index) or 6.977E+5 L/kg (from Log Kow). These estimates were made by EPI4.0 and based on the chemical's structure alone. Inclusion of EBTBP's measured vapor pressure and melting point, alone or in cominbation, did not alter the estimate. The estimates indicate EBTBP can be expected to be highly bound to organic carbon.
