(S) - (+) - 1,2-propanediol 丨 CAS 4254-15-3

(S) - (+) {{- 1,2-propanediol yog chiral diol dav siv nyob rau hauv cov chaw tsim khoom, tshuaj lom neeg, thiab kev lag luam polymer. Nws ua haujlwm rau qhov tseem ceeb hauv synthesis ntawm enantiomerically ntshiab teb, suav nrog chiral cov kuab tshuaj, muaj cov khoom xyaw carraceutical (APIs), thiab tshuaj tshwj xeeb. Hauv kev siv tshuaj chemicalcution, nws tau ua haujlwm rau kev tsim cov beta-blockers, cov tshuaj pleev thaiv cov tshuaj pleev cov sawv cev, thiab lwm yam tshuaj uas rhiab. Nws cov pab pawg hydroxyl kuj tso cai rau nws daim ntawv thov hauv polymer synthesis, suav nrog cov polymer synthesis, suav nrog cov polymer, polyurethanes, thiab epoxy resins, uas nws pab txhawb kom txhim kho kom tau zoo thiab ua haujlwm. Ib qho ntxiv, nws yog siv rau hauv kev tsim cov tshuaj pleev ib ce, cov khoom noj khoom haus ntxiv, thiab ua cov kuab tshuaj nyob hauv ntau cov txheej txheem muaj kev muaj.

Cov txiaj ntsig ntawm (s) - (+)- 1,2 {{{}} purity, siab purity, thiab multifunctional reactivity. Nws cov (s) -Configuration ua rau kev tsim cov sterochemically txhais tau cov tebchaw, uas yog qhov tseem ceeb rau cov tshuaj uas yuav tsum muaj rau kev ua tau zoo thiab kev nyab xeeb. Nws ob pab pawg hydroxyl muab cov tshuaj lom neeg feem ntau rau Esterification, etherification, thiab polymerization kev tawm tsam. Cov compound yog dej-soluble, ruaj khov nyob rau hauv cov qauv ntawm cov qauv, thiab cov tshuaj tiv thaiv ntau yam, ua rau yooj yim rau kev kuaj thiab hluav taws xob. Cov khoom siv no tso nyiaj tau zoo, reproducible, thiab nkag tau tej hom phiaj molecules hla ntau cov haujlwm.
