Additional information

The purpose of this study was to determine the melting temperature of the test substance, Butyl Phosphorothioic Triamide (NBPT). The study was conducted as described in the ABC study protocol entitled "Determination of Melting Point/Melting Range for Butyl Phosphorothioic Triamide (NBPT)", which was patterned after the Organization for Economic Cooperation and Development, Guideline for the Testing of Chemicals No. 102 (2) and the Official Journal of the European Communities, Part A.1, Methods for the Determination of Physico-Chemical Properties, Melting/Freezing Temperature . The study was conducted in compliance with the GLP standards of the OECD.
