Materials and methods

Test guideline
Guideline:
other: Accepted calculation method by KOCWIN v2.00 © 2000 U.S. Environmental Protection Agency
Principles of method if other than guideline:
A "fragment constant" methodology is used to predict the log KOC. For this, a structure is divided into fragments (atom or larger functional groups) and coefficient values of each fragment or group are summed together to yield the log KOC estimate.
GLP compliance:
no
