Amides

N,N-Bis(2-hydroxyethyl)dodecanamide is a surfactant that is used in the treatment of wastewater. It has been shown to be effective at removing p-hydroxybenzoic acid from water and at reducing the concentration of this compound in the environment. N,N-Bis(2-hydroxyethyl)dodecanamide also has antimicrobial properties and synergizes with other antimicrobial agents to provide a more potent effect than when it is used alone. This surfactant has been shown to have an effect on congestive heart failure by blocking the action of angiotensin II receptors.

Dithiooxamide is a chemical compound that contains two sulfur atoms, one oxygen atom, and one nitrogen atom. It has been shown to be an effective treatment for wastewater by removing nitrogen and phosphorus. Dithiooxamide binds to metal ions such as copper and iron in the water, forming a complex. This process prevents the metal ions from being available as catalysts in the oxidation of organic pollutants. The binding of dithiooxamide with these metals also removes them from wastewater, preventing them from being taken up by plants or animals. Dithiooxamide can be used to remove malonic acid (a carcinogen) and p-nitrophenyl phosphate (a liver toxin) from blood samples for analysis using electrochemical impedance spectroscopy, which relies on the ability of dithiooxamide to bind to these chemicals. Dithiooxamide is also used as a surfactant in analytical chemistry methods such as gas chromatography or liquid chromatography because it
