2-Aminopyridine Usage And Synthesis
Chemical Propertiescream to light yellow-beige crystalline powder,
Chemical Properties2-Aminopyridine is a flammable, colorless crystalline solid, or white leaflets or powder, or colorless liquid with a characteristic odor
Physical propertiesColorless to yellow crystals, leaflets, flakes, or powder with a characteristic odor. May darken after prolonged storage.
UsesUsed to label neutral and acidic glycans for fluorescent and UV detection in HPLC.1 2-AP has also been used to derivatize sialyloligosaccharides for detection in FAB-MS.2
UsesCompound has been shown to reversibly block voltage-dependent potassium channels, and is also a common impurity from the synthesis of compounds found in hair dyes
UsesThe main use of 2-aminopyridine is in manufacturing pharmaceuticals such as antihistamines.
General DescriptionWhite powder or crystals or light brown solid.
Air & Water ReactionsDecomposes in air. Soluble in water.
Reactivity Profile2-Aminopyridine 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. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. Reacts with oxidizing agents .
Fire Hazard2-Aminopyridine is combustible.
Safety ProfilePoison by ingestion, inhalation, subcutaneous, intravenous, and intraperitoneal routes. Toxic effects resemble strychnine poisoning. Human systemic effects by inhalation: somnolence, convulsions, and antipsychotic effects. Human central nervous system effects by inhalation. When heated to decomposition it emits highly toxic fumes of NOx,.
Potential Exposure2-Aminopyridine is used in the manufacture of pharmaceuticals; especially antihistamines.
Environmental fateSoil. When radio-labeled 4-aminopyridine was incubated in moist soils (50%) under aerobic conditions at 30 °C, the amount of 14CO2 released from an acidic loam (pH 4.1) and an alkaline, loamy sand (pH 7.8) was 0.4 and 50%, respectively (Starr and Cunningham, 1975).
Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and Lewis, 1987).
ShippingUN2671 Aminopyridines, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Purification MethodsIt crystallises from *benzene/pet ether (b 40-60o) or CHCl3 /pet ether. [Beilstein 22/8 V 280.]
IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides
Waste DisposalIncineration with nitrogen oxides removal from effluent gas.
