Chlorpheniramine maleate Synonyms: 1-(p-Chlorophenyl)-1-(2-pyridyl)-3-dimethy-laminopropanebimaleate;1-(p-chlorphenyl)-1-(2-pyridyl)-3-dimethylaminopropanmaleat;2-(p-chloro-alpha-(2-(dimethylamino)ethyl)benzyl)-pyridinmaleate(1:1);allerclor;allergin;alunex;antagonate;carbinoxamidemaleate CAS: 113-92-8 MF: C20H23ClN2O4 MW: 390.86 EINECS: 205-054-0 Product Categories: Intermediates & Fine Chemicals;Pharmaceuticals;Antagonists;Histaminergics;Neurotransmitters mp : 130-135 °C(lit.) Water Solubility: 1-5 g/100 mL at 21 ºC Chemical Properties: White Solid Usage: Antihistaminic General Description :Odorless white crystalline solid or white powder with a bitter taste. pH (2% aqueous solution) 5. pH (1% aqueous solution) 4-5. Air & Water Reactions :Water soluble. Reactivity Profile: 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. Fire Hazard: Flashpoint data for Chlorpheniramine maleate are not available; however, Chlorpheniramine maleate is probably combustible.
