Applicatio:

Acidum hydroxybenzoicum 4-, etiam p-acidi hydroxybenzoici (PHBA) CAS 99-96-7, est acidum monohydroxybenzoicum, derivatio phenolica acidi benzoici.Est solidum album crystallinum, quod in aqua et chloroforme leviter solutum est, sed solubile in solventibus polari organicis sicut alcohols et acetone.4-Acidum hydroxybenzoicum imprimis notum est fundamentum praeparationis eius estorum, qui parabens appellati sunt, quae in medicaminibus et quibusdam ophthalmicis solutionibus adservativa adhibentur.Isomeric est cum acido 2-hydroxybenzoico, noto acido salicylico, praecursore ad aspirin, et cum acido 3-hydroxybenzoico.4-Acidum hydroxybenzoicum medium adhibetur pro fucis, antisepticis et medicamentis pharmaceuticis activum.Adhibetur etiam ut cibus conservans, corrosio inhibitoris, anti-oxidantis et emulsiantis.Reagit cum acido 6-hydroxynaphthaleno 2-carboxylico ad praeparandum polyester, qui vocatur Vectran fibra aromatica.Agit praecursorem ad praeparandum p-hydroxyphenylbenzoate, p-acetoxybenzoyl chloridum et 4,4'-Dihydroxybenzophenone.Praeterea, in fucis additivis, adiectivis efficiens, auxiliis processus, electricis et electronicis productis adhibitis.Adde quod in fucis et quibusdam solutionibus ophthalmicis conservativum agit.4-Acidum hydroxybenzoicum magni momenti commercialis est.
