Abstract
A dose range-finding developmental toxicity study was conducted with 1,2- benzenedicarboxylic acid, di-C6-8-branched alkyl esters, C7 rich (CAS No.71888- 89-6) for the purpose of selecting dose levels for a subsequent definitive study in rats. Because the in-life phase of the range-f inding study was just recently completed, a QA'd report is not yet available. It should be emphasized that because this study was a dose range-finding study, observations should be considered preliminary - a more definitive assessment will require completion of a full developmental toxicity study with a larger number of mated females and more indepth fetal evaluations. The test substance was diluted with corn oil and admmistered by oral gavage to 7 inseminated female rats/group, on gestation days 6-20, at dose levels of 0, 250, 500, 750, and 1000 mg/kg/day. Control animals received corn oil only. All females were sacrificed on gestation day 21 and subjected to Cesarean section. Uteri were removed, weighed, and examined for the number of live fetuses, dead fetuses, and resorptions. Fetuses were sexed, weighed, and examined for external malformations.
