High impact information on Didodecyldimethylammonium

  • Short silica-based monolithic columns (0.5-1 cm) are coated with the surfactant didodecyldimethylammonium bromide (DDAB) and used for fast ion exchange separations of small inorganic anions [1].
  • A liquid chromatography-tandem mass spectrometry method has been developed for the determination of residues of alkylbenzyldimethylammonium, didecyldimethylammonium, didodecyldimethylammonium, and benzyldodecylhydroxyethylammonium compounds in various food matrixes [2].
  • In addition, the isolate also utilized didodecyldimethylammonium salt, ditetradecyldimethylammonium salt and alkyltrimethylammonium salts (C10 to C18) as sole source of carbon and energy [3].

Analytical, diagnostic and therapeutic context of Didodecyldimethylammonium

  • Contents of Na+ and Cl- ions in the complexes evaluated from the atomic absorbance for Na+ and the potentiometry for Cl- revealed charge molar ratios of OTA/DNA = 1 and DDA/DNA = 1.25 [4].
