Tha searbhag 4-Hydroxybenzoic, ris an canar cuideachd searbhag p-Hydroxybenzoic (PHBA) CAS 99-96-7, na searbhag monohydroxybenzoic, toradh phenolic de searbhag benzoic.Is e cruth geal criostalach a th’ ann a tha beagan solubhail ann an uisge agus cloroform ach nas so-sgaoilte ann an solventan organach pòlach leithid alcohols agus acetone.Tha 4-Hydroxybenzoic Acid air ainmeachadh gu sònraichte mar bhunait airson a bhith ag ullachadh a eòrna, ris an canar parabens, a tha air an cleachdadh mar stuthan-gleidhidh ann an cungaidhean maise agus cuid de fhuasglaidhean offthalmach.Tha e isomeric le searbhag 2-hydroxybenzoic, ris an canar searbhag salicylic, ro-ruithear aspirin, agus le searbhag 3-Hydroxybenzoic.Tha searbhag 4-Hydroxybenzoic air a chleachdadh mar eadar-mheadhanach airson dathan, antiseptics agus grìtheidean cungaidh-leigheis gnìomhach.Tha e cuideachd air a chleachdadh mar stuth gleidhidh bìdh, meirg inhibitor, anti-oxidant agus emulsifier.Bidh e ag ath-fhreagairt le searbhag 6-hydroxynaphthalene-2-carboxylic gus polyester cùbhraidh ris an canar Vectran fiber ullachadh.Bidh e ag obair mar ro-ruithear airson p-hydroxyphenylbenzoate ullachadh, p-acetoxybenzoyl chloride agus 4,4’-Dihydroxybenzophenone.Nas fhaide, tha e air a chleachdadh ann am peant cur-ris, còmhdach cur-ris, giollachd taic, dealain is eileagtronaigeach bathar.A bharrachd air an seo, tha e ag obair mar neach-gleidhidh ann an cungaidhean maise agus cuid de fhuasglaidhean offthalmach.Tha searbhag 4-Hydroxybenzoic air leth cudromach gu malairteach.
