Hydroxybenzoic acid, kuma aka sani da p-hydroxybenzoic acid, wani fili ne na kwayoyin halitta.

Manyan kaddarorinsa sune kamar haka:

Kaddarorin jiki: Hydroxybenzoic acid fari ne ko rawaya kristal mai kamshi na musamman.

Abubuwan sinadarai: Hydroxybenzoic acid yana ɗan narkewa cikin ruwa kuma yana narkewa a cikin giya. Yana da acidic carboxylic acid wanda zai iya samar da gishiri da karafa. Hakanan yana iya amsawa tare da aldehydes ko ketones, jujjuya halayen natsuwa, da samar da mahaɗan ether.

Reactivity: Hydroxybenzoic acid na iya shan maganin neutralization tare da alkali don samar da gishiri benzoate. Yana iya shiga cikin halayen esterification a ƙarƙashin catalysis acid don samar da p-hydroxybenzoate ester. Hydroxybenzoic acid kuma matsakaici ne na masu kula da haɓakar shuka.

Aikace-aikace: Hydroxybenzoic acid za a iya amfani da su hada shuka girma regulators, dyes, fragrances, da sauran sunadarai.
