Specific cooperative effect for the enantiomeric separation of amino acids using aqueous two-phase systems with task-specific ionic liquids was written by Wu, Datong;Zhou, Ying;Cai, Pengfei;Shen, Shanshan;Pan, Yuanjiang. And the article was included in Journal of Chromatography A in 2015.COA of Formula: C4H11NO This article mentions the following:

Aqueous two-phase systems (ATPS) based on hydrophilic ionic liquid (IL) and inorganic salt solution were designed and prepared for the enantiomeric separation of racemic amino acids. Two different kinds of hydrophilic ionic liquids (I, IL-1 and II IL-2) containing functional groups were synthesized to sep. racemic amino acids. Preliminary experiments showed that D-enantiomer of amino acids cooperatively interacted with ILs, which pushed D-enantiomer to remain in the bottom IL-rich phase. By contrast, L-enantiomer was transferred into the top Na₂SO₄-rich phase. The enantioselectivity of IL-1 was better than that of IL-2 because of their different intermol. interactions. Various factors influencing separation efficiency were also systematically studied including extraction time, IL volume and temperature Also, the mechanism was studied by ¹H NMR and DFT calculations, which showed that the hydrogen bond between the carboxylate and amide groups and the resonance-assisted hydrogen bond between amino and hydroxyl groups conditioned the movement between the residues and ILs. Finally, IL-1 was validated with other general amino acids by the same procedures based on ATPS. In the experiment, the researchers used many compounds, for example, (R)-2-Aminobutan-1-ol (cas: 5856-63-3COA of Formula: C4H11NO).

(R)-2-Aminobutan-1-ol (cas: 5856-63-3) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters.

A sensitive chiral high performance liquid chromatog. (HPLC) method for the determination of aliphatic primary amino alc. isomers with o-phthaldialdehyde/mercaptoethanol precolumn derivatization has been developed and validated. Seven chiral columns were tested in a reversed phase mode. Excellent enantioseparation with the resolution more than 2.0 was achieved on Chiralcel OJ-3R. The effect of various chromatog. conditions including column temperature, acetonitrile content in the mobile phase, buffer pH, buffer concentration, and buffer type in the mobile phase on the retention and the selectivity was investigated. The final mobile phase consisted of binary mixture of 20mM ammonium formate solution with acetonitrile (75:25; volume/volume). The analyses were performed at mobile phase flow rate of 1.0 mL/min and the column temperature of 40掳C. The fluorescence detection was performed at excitation wavelength of 345 nm and emission wavelength of 450 nm. The developed method was fully validated in terms of linearity, sensitivity, accuracy, precision, intermediate precision, and selectivity according to International Council for Harmonisation of Tech. Requirements for Pharmaceuticals for Human Use guidelines using internal normalization procedure. The proposed chiral method was proved to be highly sensitive, simple, and rapid and was successfully applied to the determination of D-Valinol content in com. available samples of L-Valinol.

Enantioselective Fluorescent Recognition in the Fluorous Phase: Enhanced Reactivity and Expanded Chiral Recognition was written by Wang, Chao;Wu, Elaine;Wu, Xuedan;Xu, Xiangchuan;Zhang, Guoqing;Pu, Lin. And the article was included in Journal of the American Chemical Society in 2015.Safety of (R)-2-Aminobutan-1-ol This article mentions the following:

A novel perfluoroalkyl-BINOL-based chiral diketone is the 1st highly enantioselective fluorescent sensor in the fluorous phase. One enantiomer of a chiral amino alc. or diamine at a concentration >1 mM can cause an up to 1200-2000-fold fluorescent enhancement of the sensor (0.08 mM), while the other enantiomer gives only a 10-50-fold enhancement. The fluorous-phase-based sensor is found to enhance the reactivity of the previously reported fluorous insoluble sensor with amino alcs. and expand its chiral recognition ability. Dynamic light scattering studies show the formation of aggregates of very different particle sizes when two enantiomers of a substrate interact with the sensor in perfluorohexane (FC-12). This substantial difference enables easy discrimination of the enantiomers with UV-lamps or even the naked eye. NMR, IR, and mass spectroscopic studies indicate that the fluorescent enhancement and enantioselectivity should originate from the fluorous solvent-promoted nucleophilic addition of the amino alcs. to the carbonyl groups of the sensor. In the experiment, the researchers used many compounds, for example, (R)-2-Aminobutan-1-ol (cas: 5856-63-3Safety of (R)-2-Aminobutan-1-ol).

(R)-2-Aminobutan-1-ol (cas: 5856-63-3) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Safety of (R)-2-Aminobutan-1-ol

Diverse synthetic approaches towards C1′-branched acyclic nucleoside phosphonates was written by Kalcic, Filip;Dracinsky, Martin;Janeba, Zlatko. And the article was included in Organic & Biomolecular Chemistry in 2021.Reference of 5856-63-3 This article mentions the following:

Herein we describe and compare five convenient approaches leading to key synthetic 6-chloropurine acyclic nucleoside phosphonates (ANPs), e.g. I, bearing the 9-phosphonomethoxyethyl (PME) moiety branched at the C₁‘ position. These intermediates can be further vastly diversified into target C1′-branched ANPs bearing either natural or unnatural nucleobases. The importance of C1′-branched ANPs is emphasized by their analogy with C1’-substituted cyclic nucleotides (such as remdesivir, a broad-spectrum antiviral agent) and evaluation of their biol. activity (e.g. antiviral, antineoplastic, and antiprotozoal) will be a tempting subject of further research.
