Chemical Properties: yellow or bright yellow needle-like crystals. It can volatilize with water vapor and has the fragrance of benzaldehyde. Soluble in ethanol, ether, benzene, slightly soluble in water, flash point>110 degree, reacts hnyav nrog pyrrole.
Siv: 2-Nitrobenzaldehyde yog benzaldhyde nrog ib pab pawg nitro hloov hauv txoj haujlwm ortho. 2-Nitrobenzaldehyde yog siv rau hauv kev npaj dyes thiab colorants xws li Indigo carmine. 2-Nitrobenzaldehyde gas tau pom tias yog ib pab pawg tiv thaiv photoremovable zoo li hauv kev npaj cov khoom siv tau zoo dua xws li o-Nitrophenylethylene glycol.
Txhais: ChEBI:2-nitrobenzaldehyde yog benzaldehyde hloov ntawm ortho-txoj hauj lwm nrog ib pab pawg nitro. Nws yog C-nitro compound thiab cov tswv cuab ntawm benzaldehydes.
Daim ntawv thov: 2-Nitrobenzaldehyde tuaj yeem cuam tshuam nrog chitosan los ua 2-nitrobenzyl-chitosan, uas yog soluble hauv
trifluoroacetic acid thiab tuaj yeem ua electrospun rau hauv nanofiber matrices. Ntawm photolysis, pawg nitrobenzyl yog cleaved los tsim chitosan nanofiber matrices zoo. Tib txoj cai tau siv rau kev npaj ntawm gelatin nanofiber matrices. Thecondensation ntawm o-NBA nrog 2-aminobenzothiazole cov ntaub ntawv o-nitrobenzylidene 2-aminobenzothiazole, ib tug Schiff's puag uas yuav hnov mob nrog hlau ions los ua complexes.
