I-4-Hydroxybenzoic Acid, eyaziwa nangokuthi i-p-Hydroxybenzoic acid (PHBA) CAS 99-96-7, i-monohydroxybenzoic acid, i-phenolic derivative ye-benzoic acid.Kuyikristalu eqinile emhlophe encibilika kancane emanzini nakwi-chloroform kodwa incibilika kakhulu kuzincibilikisi zemvelo ezitholakala ezindaweni ezishisayo ezifana notshwala ne-acetone.I-4-Hydroxybenzoic Acid yaziwa ngokuyinhloko njengesisekelo sokulungiswa kwama-ester ayo, aziwa ngokuthi ama-parabens, asetshenziswa njengezilondolozi ezimonyoni nakwezinye izixazululo ze-ophthalmic.I-isomeri ene-2-hydroxybenzoic acid, eyaziwa ngokuthi i-salicylic acid, isandulela se-aspirin, kanye ne-3-Hydroxybenzoic acid.I-4-Hydroxybenzoic Acid isetshenziswa njengendawo ephakathi kumadayi, ama-antiseptics kanye nezithako ezisebenzayo zemithi.Ibuye isetshenziswe njengesilondolozi sokudla, i-corrosion inhibitor, i-anti-oxidant kanye ne-emulsifier.Ihlangana ne-6-hydroxynaphthalene-2-carboxylic acid ukuze kulungiswe i-polyester enamakha ebizwa ngokuthi i-Vectran fiber.Isebenza njengesandulela sokulungiselela i-p-hydroxyphenylbenzoate, i-p-acetoxybenzoyl chloride kanye ne-4,4'-Dihydroxybenzophenone.Ngaphezu kwalokho, isetshenziselwa izithasiselo zikapende, izithasiselo zokumboza, izinsiza zokucubungula, imikhiqizo kagesi neye-elekthronikhi.Ngaphezu kwalokhu, isebenza njengesilondolozi sezimonyo nakwezinye izixazululo ze-ophthalmic.I-4-Hydroxybenzoic Acid ibaluleke kakhulu kwezohwebo.
