Abstract

We recently received several carrot extracts from another FDA district laboratory for identification of a material present in each of the extracts which had a GLC retention time inconsistent with that of any known pesticide. The material, which was eluted from Florisil with 15% ether in petroleum ether (AOAC, par. 29.015, 1975) exhibited both electron capture and microcoulometric responses (LASKI and LEONE, 1976). This paper reports structural elucidation, GLC characteristics and recovery data for the material.
