Chemical Properties

White Solid


An antagonist of the histamine H1-receptor



brand name

Trimeton (Schering-Plough); Teldrin (GlaxoSmithKline).

General Description

Chlorpheniraminemaleate, (±)2-[p-chloro-α-[2-dimethylamino)ethyl]benzyl]pyridine bimaleate (Chlor-Trimeton), is a white crystallinepowder that is soluble in water (1:3.4), in alcohol(1:10), and in chloroform (1:10). It has a pKa of 9.2, and anaqueous solution has a pH between 4 and 5. Chlorination ofpheniramine in the para position of the phenyl ring increasespotency 10-fold with no appreciable change in toxicity.Most of the antihistaminic activity resides with thedextro isomer (see under “Dexchlorpheniramine Maleate” ).The usual dose is 2 to 4 mg 3 or 4 times a day. It has a halflifeof 12 to 15 hours.

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

Flash point data for Chlorpheniramine maleate are not available; however, Chlorpheniramine maleate is probably combustible.

Safety Profile

Poison by ingestion, intravenous, and subcutaneous routes. Experimental reproductive effects. Used as an antihistamine. Mutation data reported. When heated to decomposition it emits very toxic fumes of Cland NOx.
