1,4-Dioxane-2,5-dione CAS 502-97-6

1,4-Dioxane-2,5-dione (CAS 502-97-6), tseem hu ua glycolide, yog cyclic diester dav siv los ua monomer hauv kev sib txuas ntawm biodegradable polymers. Nws yog lub tsev thaiv tseem ceeb rau kev tsim cov polyglycolide (PGA) thiab copolymer xws li polylactide-co-glycolide (PLGA), uas tau siv dav hauv biomedical thiab kws tshuaj. Cov polymers no yog siv rau hauv absorbable sutures, tshuaj xa tshuab, cov ntaub so ntswg engineering scaffolds, thiab phais implants vim lawv tswj degradation thiab biocompatibility. Tshaj li kev siv tshuaj biomedical, 1,4-dioxane-2,5-dione yog siv rau hauv kev tshawb fawb thiab kev lag luam polymer chemistry rau kev tsim cov yas zoo ib puag ncig thiab cov ntaub ntawv ua tau zoo. Nws cov qauv cyclic tso cai rau lub nplhaib-qhib polymerization, ua rau kev tsim cov polymers nrog cov khoom hnyav molecular thiab cov khoom siv kho tshuab.

Cov txiaj ntsig ntawm 1,4-dioxane-2,5- dione qia los ntawm nws cov qauv ester reactive, biocompatibility, thiab muaj peev xwm tsim biodegradable polymers. Nplhaib-qhib polymerization ntawm cov monomer no ua rau muaj kev tswj xyuas meej ntawm cov saw hlau ntev, muaj pes tsawg leeg, thiab crystallinity, tso cai rau kev hloov kho rau kev siv tshuaj biomedical lossis kev lag luam. Cov polymers uas tshwm sim yog ib txwm degraded rau hauv cov khoom tsis muaj tshuaj lom, xws li glycolic acid, txo kev cuam tshuam ib puag ncig thiab txhim kho kev nyab xeeb hauv kev siv kho mob. Nws cov purity siab thiab kwv yees reactivity txhim kho synthesis efficiency thiab reproducibility, ua rau nws haum rau ob qho tib si kuaj-scale kev tshawb fawb thiab loj-scale industrial ntau lawm. Tsis tas li ntawd, nws cov versatility nyob rau hauv copolymerization txhawb kev tsim cov ntaub ntawv nrog ib tug sib npaug ntawm txhua yam muaj zog, yooj, thiab degradation tus nqi.
