Specification

1.Air & Water Reactions : 6-Aminonicotinamide (CAS NO. 329-89-5) is insoluble in water.
2.Reactivity Profile: An amine and amide. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P₂O₅ or SOCl₂ generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
3.Health Hazard :Acute/Chronic hazards: When heated to decomposition 6-Aminonicotinamide (CAS NO. 329-89-5) emits toxic fumes of NOx.
4.Fire Hazard : 6-Aminonicotinamide (CAS NO. 329-89-5) is probably combustible.
