5,7-Dihydroxy-4-methylcoumarin Usage And Synthesis
Chemical Properties White metallic powder
General Description Yellow powder. Fluoresces blue. Absorbs ultraviolet light.
Air & Water Reactions Slightly water soluble .
Reactivity Profile 5,7-Dihydroxy-4-methylcoumarin is a phenol and lactone. 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. Lactones react similarly to esters. 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 5,7-Dihydroxy-4-methylcoumarin are not available. 5,7-Dihydroxy-4-methylcoumarin is probably combustible.
