Application of 4254-15-3, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 4254-15-3, Name is (S)-Propane-1,2-diol,introducing its new discovery.
Synthesis of novel C2-symmetric chiral crown ethers and investigation of their enantiomeric recognition properties
A series of new C2-symmetric chiral aza crown ether macrocycles 1-4 have been synthesized from (S)-3-aryloxy-1,2-propanediol and (S)-1,2-propanediol for the enantiomeric recognition of amino acid ester derivatives. These new macrocycles have been shown to be strong complexing agents for primary organic ammonium salts (with K up to 176.93 M-1 and DeltaG up to 12.81 kJ mol-1) by 1H NMR titration. These macrocyclic host exhibited enantioselective bonding toward the d-enantiomer of phenylalanine methyl ester hydrochloride with KD/KL up to 6.87 in CDCl3 with 0.25% CD3OD.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 4254-15-3, and how the biochemistry of the body works.Application of 4254-15-3
