4-Hydroxybenzoic acid Usage And Synthesis
Chemical PropertiesWHITE TO BEIGE CRYSTALLINE POWDER
Chemical Properties4-Hydroxybenzoic acid is an odorless white crystalline astringent powder. In pure form, it imparts a sweetish taste at first, which quickly becomes acrid and disagreeable
OccurrenceReportedly present in apple juice, black currant, cheese, beer, grape brandy, rum, sherry, wines, cocoa, peanut, soybean and wort.
Usesp-Hydroxybenzoic acid is of significant commercial importance. The most familiar application is the use of several of its esters as preservatives, known as parabens. Also of interest is the use in liquid crystal polymer applications.
UsesAcetylsalicylic Acid Impurity A
UsesIn organic. syntheses; intermediate for dyes, fungicides.
DefinitionChEBI: A monohydroxybenzoic acid that is benzoic acid carrying a hydroxy substituent at C-4 of the benzene ring.
PreparationPrepared from p-bromophenol or p-hydroxybenzaldehyde, or from saponification of methyl salicylate, a major component of oil of wintergreen.
Aroma threshold valuesDetection at 5 ppm (water)
