Axially chiral amino acid scaffolds as efficient fluorescent discriminators of methanol-ethanol was written by Bag, Subhendu Sekhar;Jana, Subhashis. And the article was included in New Journal of Chemistry in 2017.Recommanded Product: tert-Butyl (3-ethynylphenyl)carbamate This article mentions the following:
The authors report a unique fluorescence sensor based on an axially chiral unnatural triazolyl aromatic amino acid scaffold (ArTAA) for discrimination of methanol from ethanol via a switch on fluorescence response. All three sensors, the simple scaffold (ArTAA), and the mono- (PyAm-ArTAA) and bis-pyrenyl- (Py2Am-ArTAA) amides, show similar sensitivity and detection limit ranging from 0.5-2.1 volume/volume% of ethanol. The solid films of these sensors also are effective in sensing ethanol vapor via generation of a distinct and enhanced fluorescence signal. All the authors’ exptl. results suggest the role of axial chirality of the hairpin-shaped scaffold in differential solvation guided H-bonding interaction and discriminating between ethanol and methanol with a switch-on fluorescence response. In the experiment, the researchers used many compounds, for example, tert-Butyl (3-ethynylphenyl)carbamate (cas: 185619-66-3Recommanded Product: tert-Butyl (3-ethynylphenyl)carbamate).
tert-Butyl (3-ethynylphenyl)carbamate (cas: 185619-66-3) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: tert-Butyl (3-ethynylphenyl)carbamate
