• synthetic
  • Acridine and its derivatives can be prepared by many synthetic processes. (wikipedia.org)
  • Some noteworthy developments: 1818: Brugnatelli isolates alloxan from uric acid 1832: Dobereiner produces furfural (a furan) by treating starch with sulfuric acid 1834: Runge obtains pyrrole ("fiery oil") by dry distillation of bones 1906: Friedlander synthesizes indigo dye, allowing synthetic chemistry to displace a large agricultural industry 1936: Treibs isolates chlorophyl derivatives from crude oil, explaining the biological origin of petroleum.

  • orange
  • The resulting complexes were further conjugated by derivatives of acridine orange (AO) as fluorescent labels under the same conditions to form [AO:Poly-X:A-AM silane]/SiO 2 complexes. (mdpi.com)
  • Acridine orange (3,6-dimethylaminoacridine) is a nucleic acid-selective metachromatic stain useful for cell cycle determination. (wikipedia.org)
  • In the course of the passages it lost its O antigen and in 1953 was cured first of its lambda phage (strain W1485 by UV by Joshua Lederberg and colleagues) and then in 1985 of the F plasmid by acridine orange curing. (wikipedia.org)
  • They applied high alternating voltages in air to materials such as acridine orange, either deposited on or dissolved in cellulose or cellophane thin films. (wikipedia.org)
  • benzene
  • The most influential proposal was that of KekulĂ© who in 1865 suggested a cyclic structure of six carbon atoms with alternating single and double bonds KekulĂ© based his argument on the now well-known observations of arene substitution patterns, namely that there are always only one isomer of any monoderivative of benzene and three isomers of every disubstituted derivative.
