Uses

Used in Pest Control Applications:
DiMethyl 4,4'-dinitro-[1,1'-biphenyl]-2,2'-dicarboxylate is used as a pheromone-based attractant for houseflies to control their population. It is particularly effective in agricultural and residential settings where housefly infestations can be problematic.
Used in Agricultural Industry:
In the agricultural industry, Muscalure is used as a pest management tool to attract and control the population of houseflies, thereby reducing the need for chemical pesticides and their associated environmental impacts.
Used in Residential Settings:
In residential settings, Muscalure is used to manage housefly infestations by attracting and trapping male houseflies, disrupting their breeding behavior and reducing the overall housefly population.
It is important to handle Muscalure with care due to its toxicity to aquatic organisms and potential for skin irritation. Proper safety measures should be taken during its application to minimize any adverse effects on the environment and human health.

Chemically Fueled Transient Geometry Changes in Diphenic Acids

Transient changes in molecular geometry are key to the function of many important biochemical systems. Here, we show that diphenic acids undergo out-of-equilibrium changes in dihedral angle when reacted with a carbodiimide chemical fuel. Treatment of appropriately functionalized diphenic acids with EDC (N-(3-(dimethylamino)propyl)-N′-ethylcarbodiimide hydrochloride) yields the corresponding diphenic anhydrides, reducing the torsional angle about the biaryl bond by ～45°, regardless of substitution. In the absence of steric resistance, the reaction is well-described by a simple mechanism; the resulting kinetic parameters can be used to derive important properties of the system, such as yields and lifetimes. The reaction tolerates steric hindrance ortho to the biaryl bond, although the competing formation of (transient) byproducts complicates quantitative analysis.
