Technical Basis
This chemical has a CASRN synonym (CASRN: 29911-28-2), which is a mixture of isomers. A review of available sources identified the following acute toxicity data (LD50) for several species. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected based on the type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2. These were evaluated using factors in Tables 3.2, 3.3, and 3.4. The most preferred route and species, a rat oral LD50 was selected as the TEEL-3 basis. TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (9100 mg/kg)
This review generated TEEL values consistent with Rev. 29A.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Rat oral LD50 (9100 mg/kg)
This review generated TEEL values consistent with Rev. 29A.
