| 3-Dimethylaminophenol Usage And Synthesis |
| Chemical Properties | Brown to Purple Solid | | Uses | 3-Dimethylaminophenol can be used as neostigmine bromide intermediate and dye intermediate. | | General Description | Needles (from ligroin) or a dark gray solid. | | Air & Water Reactions | Sensitive to prolonged exposure to air. Insoluble in water. | | Reactivity Profile | An amine and phenol. 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. Phenols do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid. | | Fire Hazard | Flash point data for 3-Dimethylaminophenol are not available. 3-Dimethylaminophenol is probably combustible. |
