Chemical Properties
brown solid
General Description
White to slightly yellowish prisms or reddish brown crystalline powder.
Reactivity Profile
N-PHENYL-1-NAPHTHYLAMINE(90-30-2) neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Air & Water Reactions
May be sensitive to prolonged exposure to air. Insoluble in water. Napthyl amines can be slowly hydrolyzed, releasing NH3 as a byproduct [N.L. Drake, Org. React. 1, (1942), 105].
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes.
Fire Hazard
Flash point data for this compound are not available. N-PHENYL-1-NAPHTHYLAMINE is probably combustible.
Uses
N-Phenyl-1-naphthylamine can be used as fluorescent probe for the determination of critical micelle concentration of surfactants. N-Phenyl-1-naphthylamine was used in a method for determination of the concentration of organolithium and organomagnesium reagents. N-Phenyl-1-naphthylamine was used as hydrophobic probe to study the phase transitions of membrane lipids in whole cells .
Definition
ChEBI: N-Phenyl-1-naphthylamine is a member of naphthalenes.
Biochem/physiol Actions
N-Phenyl-1-naphthylamine turns fluorescent after binding to hydrophobic regions of cell membranes.
Purification Methods
Crystallise it from EtOH, pet ether or *C6H6/EtOH. Dry it under vacuum in an Abderhalden pistol. [Beilstein 12 H 1224.]
