FAQ:

Daim ntawv thov:

D-(+)-Malic Acid (CAS: 636-61-3) siv los ua acidulant thiab flavoring agent, zaub mov additive.Thiab nws kuj yog siv nyob rau hauv qhov chaw ntawm tsawg qaub citric acid nyob rau hauv qaub qab zib.

D-(+)-Malic Acid (CAS: 636-61-3) yog ib qho tseem ceeb plaub-carbon atoms chiral pas dej ua ke.Nws yog tsuas yog siv nyob rau hauv ntau lub teb xws li chiral pharmaceuticals, chiral additives thiab chiral auxiliaries.Nws yog siv los ua chiral pas dej ua ke ntawm chiral synthesis hauv kev lag luam tshuaj thiab zaub mov.Raws li optically active organic acid, nws yog insubstitutable nyob rau hauv asymmetry synthesis ntawm ib co chiral tebchaw.

Qhov tshwm sim ntawm isomer yog L-daim ntawv uas tau pom nyob rau hauv txiv apples thiab ntau lwm txiv hmab txiv ntoo thiab nroj tsuag.Xaiv α-amino tiv thaiv reagent rau amino acid derivatives.Ntau yam synthon rau kev npaj cov tshuaj chiral suav nrog κ-opioid receptor agonists, 1α,25-dihydroxyvitamin D3 analogue, thiab phoslactomycin B.
