Description of key information

In the defined HPLC assay of OECD Guideline 121, a chromatographic peak for the test

material was observed at a retention time of approximately 2.8 minutes, which correlates

to an estimated log Koc value of 3.1. The estimated log Koc value using the structureproperty

relationship described in the US EPA KocWIN software (USEPA, 2012) is log

Koc = 3.03, which agrees with the measured value. The 2-butoxyethyl benzoate

substance is therefore concluded to have moderate affinity for partitioning from water to

organic matter associated with soil, sediment, and activated sludge biosolids.
