General description
Ammonium lauryl sulfate is an anionic surfactant consisting of a nonpolar hydrocarbon chain and a polar sulfate end group. It is used as a foaming agent, and as a detergent in many industrial applications.
Application
Ammonium lauryl sulfate can be used as:
- A catalyst in the synthesis of 1H-benzo[d]imidazole, quinoxaline, and 2,3-dihydro-1H-benzo[b][1,4]diazepine derivatives by reacting with benzene-1,2 diamine and aromatic aldehydes/1,2-diketones/ketones respectively.
- A corrosion inhibitor for carbon steel and copper in acidic solution.
- A surfactant in the fabrication of porous ceramics by gel casting.

Endotoxins (lipopolysaccharides, LPSs) are components of the envelope of Gram-negative bacteria. These molecules, responsible for both advantageous and harmful biological activities of these microorganisms, are highly immunogenic and directly involved in numerous bacterial diseases in humans such as Gram-negative sepsis.

Rhizobium leguminosarum is a Gram-negative bacterium that forms nitrogen-fixing symbioses with compatible leguminous plants via intracellular invasion and establishes a persistent infection within host membrane-derived subcellular compartments. Notably, an unusual very-long-chain fatty acid (VLCFA) is found in the lipid A
