Acridine 0.75-hydrate

The title compound, C(13)H(9)N·0.75H(2)O was obtained during a study of the polymorphic system of acridine, by slow evaporation from an ethanol-water solution. There are two acridine mol-ecules (indicated by I and II, respectively) and one and a half water mol-ecules in the asymmetric unit. The half-mol-ecule of water is located on a crystallographic twofold axis. The crystal structure is built...

Phenyl acridine-9-carboxyl­ate

The acridine ring system and the benzene ring in the title compound, C(20)H(13)NO(2), are oriented at a dihedral angle of 6.4 (2)°. The carboxyl group is twisted at an angle of 83.6 (2)° relative to the acridine skeleton. The mol-ecules in the crystal are arranged in stacks along the b axis, with two of the acridine rings involved in multiple π-π inter-actions [centroid-centroid distances in th...

Investigating the binding of acridine, acridine orange, and acridine yellow G to humic acid through fluorescence quenching.

A fluorescence quenching method was used to determine the equilibrium binding constants for the association of acridine, acridine orange, and acridine yellow G to humic acid. The fluorescence of each polycyclic aromatic nitrogen heterocycle (PANH) was monitored as aliquots of humic acid were added, and a Stern-Volmer plot was produced in which the slope is the equilibrium constant of the bindin...

Chloral hydrate

Major uses Chloral hydrate (synthesized in 1832 and introduced into medicine 1869) is the oldest member of sedative-hypnotic drugs. To the same group belong paraldehyde, bromide, urethane, and sulfonal. Metabolite of chloral hydrate, trichloroethanol, is also an excellent hypnotic agent, but is not often used as such due to its physical and irritant properties. At present, chloral hydrate is la...
