Kini glycoxylic acid?

Glyoxylic acid, ti a tun mọ ni formoic acid, hydrated glyoxylic acid ati oxyacetic acid, ilana kemikali C2H203, jẹ aldehyde acid ti o rọrun julọ, eyiti o wa ninu awọn eso ti ko dagba, awọn ewe alawọ ewe tutu ati awọn beets suga. Awọn kirisita lati omi jẹ awọn kirisita monoclinic (ti o ni 1/2 omi gara). Iwọn molikula ibatan jẹ 70.04. Ojuami yo jẹ 98 ℃. O ni itọwo ti ko dun. O jẹ acid ipata to lagbara, eyiti o rọrun lati deliquescence ati pe o le ṣe lẹẹmọ nigbati o ba farahan si afẹfẹ. O jẹ tiotuka diẹ ninu ethanol, ether ati benzene, ati pe o le jẹ tiotuka larọwọto ninu omi. Ojutu olomi jẹ iduroṣinṣin ati pe ko bajẹ ni afẹfẹ. O wa ninu ojutu olomi ni irisi hydration.
