Glyoxylic acid CAS 298-12-4
Glyoxylic acid CAS 298-12-4 , kuma aka sani da formoic acid, hydrated glyoxylic acid da oxyacetic acid, sinadaran dabara C2H203, shi ne mafi sauki aldehyde acid, wanda ya wanzu a cikin m 'ya'yan itatuwa, m koren ganye da kuma sugar beets. Lu'ulu'u daga ruwa sune lu'ulu'u na monoclinic (wanda ya ƙunshi 1/2 ruwa crystal). Nauyin kwayoyin dangi shine 70.04. Matsakaicin narkewa shine 98 ℃. Yana da ɗanɗano mara daɗi. Yana da acid mai ƙarfi mai lalata, wanda ke da sauƙin ɓata lokaci kuma yana iya yin manna idan an fallasa shi cikin iska. Yana da ɗan narkewa a cikin ethanol, ether da benzene, kuma yana iya zama mai narkewa cikin ruwa kyauta. Maganin ruwa mai ruwa yana da ƙarfi kuma baya lalacewa a cikin iska. Yana wanzu a cikin maganin ruwa a cikin nau'in hydration. Yana iya amsawa da yawancin karafa sai bakin karfe. Yana da kaddarorin acid da aldehyde.
