Benzoic acid yog qhov yooj yim tus tswv cuab ntawm tsev neeg muaj ntxhiab carboxylic acid. Nws yog cov kua qaub qaug zog uas yog qhov ua ntej rau cov synthesis ntawm ntau cov tseem ceeb organic sib txuas. Ntau tshaj li 90 feem pua ​​ntawm cov lag luam benzoic acid tau hloov pauv ncaj qha rau phenol thiab caprolactam. Nws siv nyob rau hauv kev tsim khoom ntawm glycol benzoates rau daim ntawv thov ntawm plasticizer hauv cov nplaum tsim cov khoom lag luam zuj zus. Cov organic sib xyaw ua ke tseem siv hauv kev tsim cov alkyd resins thiab drilling av nkos additive rau cov ntawv thov roj rov qab. Nws kuj tseem siv los ua cov roj hmab polymerization activator, rov ua kom zoo dua, resins, alkyd xim, yas ntim khoom, tshuaj pleev plhu, thiab cov khoom yas. Benzoic acid thiab nws cov esters tshwm sim hauv apricots, cranberries, nceb thiab nroj tsuag jasmine. Keeb kwm ntawm benzoic acid hnub rov qab mus txog rau lub xyoo pua. Nyob rau hauv lub xyoo ntawm 1875 Salkowski ib tus kws tshawb fawb muaj koob npe pom nws lub peev xwm antifungal. Hauv cov tshuaj, benzoic acid yog qhov tseem ceeb ntawm benzoin resin, thiab yog ib tus neeg sib xyaw ntawm Whitfield tshuaj pleev uas yog siv rau kev kho mob ntawm daim tawv nqaij fungal xws li tinea, mob txhab txiag, thiab kis las' s ko taw.
