I-Citraconic anhydride (Alpha-methylmaleicanhydride)

Ubume bekhemikhalis

Citraconic anhydridelulwelo olucacileyo olungenambala ukuya kumthubi okhanyayo, lula ukubola emanzini, kwaye luzinzile kubushushu begumbi kunye noxinzelelo.Citraconic anhydrideinobuntununtunu kwaye kufuneka ivalwe kwaye igcinwe kwindawo epholileyo neyomileyo.

Usetyenziso

I-Citraconic anhydride isetyenziswa njenge-monomer kwi-specialty unsaturated polyester resins.Isetyenziselwa ukulungiselela i-bicyclic pyrrolidines, i-maleimides kunye ne-co- kunye ne-terpolymers.Ikwasetyenziselwa ukukhusela i-N-terminal amino acids.Ngapha koko, kubandakanyeka ekulungiseleleni iimpahla ze-ping acid kunye ne-amide yayo.Ukongeza koku, isetyenziselwa ngokukhethekileyo ukwahlukaniswa kwe-histidyl peptides.
