ʻO ka waikawa Glyoxylic, i ʻike ʻia hoʻi ʻo formic acid, hydrated acetic acid, a i ʻole oxoacetic acid, me ke ʻano kemika C2H203, ʻo ia ka waikawa aldehyde maʻalahi loa i loaʻa i nā hua ʻōpiopio, nā lau ʻōmaʻomaʻo palupalu, a me nā beets kō. ʻO ka crystallization mai ka wai he ʻōnaehana kristal monoclinic (loaʻa ka 1/2 crystal wai). ʻO ke kaumaha molekala pili he 70.04. He 98 ℃ ka heheʻe. He ʻala ʻoluʻolu ʻole kona, he waikawa corrosive loa, maʻalahi ka deliquescent, a hiki ke hana i kahi paste ke hōʻike ʻia i ka lewa. Hoʻoheheʻe iki ʻia i ka ethanol, ether, a me benzene, hiki ke hoʻoheheʻe manuahi i ka wai, a paʻa ka hopena wai a ʻaʻole e hōʻino i ka lewa. Loaʻa ia ma ke ʻano o ka hydration i loko o ka hopena wai. Koe wale nō ke kila kila, hiki iā ia ke hana me ka hapa nui o nā metala. Loaʻa iā ia nā waiwai acidic a me aldehyde. Hiki ke hoʻohui ʻia me ka sodium bisulfite a i ʻole ka hydrocyanic acid, e pane me ka hydroxylamine a i ʻole phenylhydrazine e hana i ka oxime a i ʻole hydrazone, e hana i ka hopena aniani kālā, hiki ke hana i ka hopena Conicoro, a hiki nō hoʻi ke hana i nā paʻakai carboxylate a me nā esters.

Hoʻohana
Hiki ke hoʻohana ʻia ka waikawa Glyoxalic i ke kūkulu ʻana o nā ʻano hopena like ʻole.
Hoʻohana ʻia ka waikawa Glyoxylic i ka hopena Hopkins Cole, kahi i hoʻohana ʻia no ka ʻike ʻana i ka tryptophan i loko o nā protein.
Hoʻopili ia me ka phenol e loaʻa ai ka 4-hydroxymandelic acid, kahi ma hope o ka hana hou ʻana me ka ammonia e hāʻawi i ka hydroxyphenylglycine, ma ke ʻano he mea mua i ka lāʻau amoxicillin.
Hoʻohana ʻia nō hoʻi ia ma ke ʻano he mea hoʻomaka no ka hoʻomākaukau ʻana o ka 4-hydroxyphenylacetic acid, kahi i hoʻohana ʻia e loaʻa ai ka atenolol.
Ka hoʻopili ʻana
250KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
