ECHEMI Editorial Reference

Butamben is a long-duration local anesthetic used for the treatment of chronic pain.
N-butyl-p-aminobenzoate is a yellow powder. Insoluble in water. (NTP, 1992)
N-butyl-p-aminobenzoate is a yellow powder. Insoluble in water. (NTP, 1992)|Butamben is an amino acid ester resulting from the formal condensation of the carboxy group of 4-aminobenzoic acid with the hydroxy group of butan-1-ol. Its local anaesthetic properties have been used for surface anaesthesia of the skin and mucous membranes, and for relief of pain and itching associated with some anorectal disorders. It has a role as a local anaesthetic. It is a benzoate ester, a substituted aniline, an amino acid ester and a primary amino compound. It derives from a 4-aminobenzoic acid and a butan-1-ol. It is a conjugate base of a butamben(1+).|Butamben is a local anesthetic in the form of n-butyl-p-aminobenzoate. Its structure corresponds to the standard molecule of a hydrophilic and hydrophobic domain separated by an intermediate ester found in most of the local anesthetics. Due to its very low water solubility, butamben was considered of low usability as it is only suitable to be used as a topical anesthesia. This belief changed with the introduction of epidural suspensions of butamben. All butamben-containing products were removed from the market under the belief that it is unsafe or ineffective.

Reactive Group:

Reactivity Profile:

N-BUTYL-P-AMINOBENZOATE is an aminophenyl ester derivative. 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.
