2-Aminopyridine Chemical Properties,Uses,Production

Chemical Properties

cream to light yellow-beige crystalline powder,

Chemical Properties

2-Aminopyridine is a flammable, colorless crystalline solid, or white leaflets or powder, or colorless liquid with a characteristic odor


Used 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


Compound 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

General Description

White powder or crystals or light brown solid.

Air & Water Reactions

Decomposes in air. Soluble in water.

Reactivity Profile

2-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 Hazard

2-Aminopyridine is combustible.

Safety Profile

Poison 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 Exposure

2-Aminopyridine is used in the manufacture of pharmaceuticals; especially antihistamines.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit


UN2671 Aminopyridines, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Purification Methods

It crystallises from *benzene/pet ether (b 40-60o) or CHCl3 /pet ether. [Beilstein 22/8 V 280.]


Incompatible 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 Disposal

Incineration with nitrogen oxides removal from effluent gas.
