Description 


A halogenated amine, ester. 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. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.



Usage 


1. The anti-histamine effect of the goods more than diphenhydramine and promethazine, the amount of small, mild side effects. For urticaria, vasodilatous rhinitis, colds, asthma, rhinitis, contact dermatitis, but also for drugs and food caused by allergies, insect bite and halo and so on.
2. Antihistamines. Similar to cricotidine, bromopyramide is also resistant to histamine. The production method of bromopidine is also similar to that of cricotidine, except that the starting material is replaced with a bromobenzene compound.
3. Used as an antistatic agent



Application
