ʻO ka Oxazole-5-carboxylic acid he mea hoʻohuihui. Hiki ke hoʻoheheʻe ʻia ka ʻakika Oxazole-5-carboxylic i ka wai a me nā mea hoʻoheheʻe kūlohelohe e like me nā ʻona a me nā eter.
Ma ka mahiʻai, hiki ke hoʻohana ʻia ka oxazole-5-carboxylic acid ma ke ʻano he synthetic raw material no nā fungicides a me nā herbicides.

Nui nā ala e hoʻomākaukau ai i ka oxazole-5-carboxylic acid. Loaʻa ke ala maʻamau e ka alkaline hydrolysis reaction o ka oxazole. Hoʻopili ʻia ka Oxazole me kahi hopena alkaline e hana i ka paʻakai, a laila hoʻololi ʻia i ka oxazole-5-carboxylic acid e ka acidification.
Hiki i ka Oxazole-5-carboxylic acid ke hoʻonāukiuki i nā maka, ka ʻili a me ka ʻōnaehana hanu, a pono e mālama ʻia ka ventila maikaʻi i ka wā o ke kaʻina hana, a pale ʻia ka pili ʻana me ka ʻili a me nā maka. ʻO ka oxazole-5-carboxylic acid he mea hiki ke puhi ʻia a pono e mālama ʻia ma kahi maloʻo a maloʻo, ma kahi mamao aku i nā kumu ahi a me nā mea ʻona. I ka lawelawe ʻana i ka oxazole-5-carboxylic acid, pono e ʻaʻahu ʻia nā mea pale kūpono e like me nā mīkina lima a me nā maka aniani e hōʻoia i ka hana palekana. I ka hihia o ka hoʻopili ʻana a i ʻole ka ʻai ʻana i ka oxazole-5-carboxylic acid, e ʻimi koke i ka lāʻau lapaʻau a lawe mai i ka ʻike huahana kūpono a i ʻole ka pahu.
