7-Oxabicyclo -heptane-2,3-dicarboxylic acid

Numerous references to derivatives of 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic acid as defoliants, herbicides, fungicides, etc., are cited in index volumes of Chem. Ahstr. since Vol. 46 (1952). 

Twenty-seven two-year-old scaleless hens were transported to Visalia, CA on October 1, 1979, housed in cages overnight with food and water provided ad lib, and exposed to field applications of DEF on October 2. Some birds were repeatedly treated over the next five days. The mature cotton fields (Diversified Farming Inc.) were sprayed from a ground vehicle that treated 8 rows simultaneously with DEF-6 (0.72 kg/l, 6 lb/gal Mobay Chemical Co.) at 0.37 gal/acre and Accelerate (amine salt of endothall (7-oxabicyclo (2.2.1) heptane-2,3-dicarboxylic acid, 0.06 kg/l, 0.5 lbs/gal) at 0.19 gal/acre in 25 gal water/acre.

Strong eluents such as sodium nitrate may be employed. The resulting chromatogram is displayed in Figure 3.171. For the analysis of herbicides lacking a chromophore such as endothall, 7-oxabicyclo[2,2,l]-heptane-2,3-dicarboxylic acid, anion-exchange chromatography with subsequent conductivity detection provides an alternative to RPLC.
