Tecnazene, also known as 2,3,5,6-tetrachloro-1-nitrobenzene or tcnb, is a member of the class of compounds known as nitrobenzenes. Tecnazene is a dual acting pesticide. It is used as a plant growth regulator to suppress sprouts on potatoes during storage and as a fungicide to prevent dry rot on the tubers. Human exposure is primarily through ingestion of food residues, with an Acceptable Daily Intake level of 0.01 mg/kg of body weight according to FAO/WHO guidelines. Tecnazene is commercially available as granules and as dispersible dust formulations.

Sample Use Guides

In Vivo Use Guide

The metabolic fate of [U-14C]-2,3,5,6-tetrachloronitrobenzene (tecnazene) has been determined in the male and female rat following a single dose of 1 mg/kg and in surgically prepared, bile-duct-cannulated rats following a single oral dose of 135 mg/kg.

Route of Administration: Oral

In Vitro Use Guide

Two doses of tecnazene dissolved in acetone, corresponding to 103 and 864 ug/cm2 of tecnazene, were applied to skin mounted on Franz diffusion cells and placed in a fume hood. Cells were either occluded withaluminumfoilorleftunoccluded.Totalabsorptionoftecnazene (dermis + receptor fluid) after 48 h was 2.2-6.1% of the applied dose for the unoccluded treatments and 22-33% for the occluded treatments. Potentially absorbed dose including all tecnazene that may have eventually permeated the skin rangedfrom 10% unoccludedto 42-53% occluded.
