[Peculiarities of detection and evaluation of the persistence of tetraethyltiuram disulfide in the biological material].

Optimal conditions for the identification and quantitative determination of tetraethyltiuram disulfide in "fresh" and putrefactive tissues of cadaverous liver are described for the purpose of TLC, HPLC, and IK-spectrophotometry following extraction of the compound of interest with ethyl acetate and its purification on a silicagel L column, 40/100 mcm. The persistence of tetraethyltiuram disulfide in the cadaverous tissues was evaluated. It was shown that the period during which tetraethyltiuram disulfide can be detected in the autopsied tissues decreases from 203 to 28 days with a rise in temperature from -15 degrees C to +36 degrees C.
