4-Aminobenzoic acid (ʻike pū ʻia ʻo ka para-aminobenzoic acid a i ʻole PABA no ka mea ua hoʻopili ʻia nā pūʻulu hana ʻelua i ke apo benzene ma waena o kekahi i kekahi ma ke kūlana para) he mea hoʻohui me ke ʻano H2NC6H4CO2H.He paʻa keʻokeʻo keʻokeʻo ʻo PABA, ʻoiai hiki ke ʻike ʻia ka hina hina.Hiki ke hoʻoheheʻe ʻia i ka wai.Loaʻa iā ia kahi apo benzene i pani ʻia me nā hui amino a me ka carboxyl.Loaʻa ka pūhui i ka honua kūlohelohe.
ʻO ka 4-Aminobenzoic acid he mea waena i ka synthesis o ka folate e ka bacteria, nā mea kanu, a me nā haʻi.
Loaʻa ka PABA i ka hoʻohana nui ʻana i ka ʻāpana biomedical.ʻO nā mea hoʻohana ʻē aʻe e pili ana i kona hoʻololi ʻana i nā mea pena azo kūikawā a me nā mea hana crosslinking.Hoʻohana ʻia ʻo PABA ma ke ʻano he pesticide biodegradable, ʻoiai ua kaupalena ʻia kona hoʻohana ʻana ma muli o ka ulu ʻana o nā ʻano hou o nā bio-pesticides.
