Quality Control of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamateIn 2020 ,《Reaction-based amine and alcohol gases detection with triazine ionic liquid materials》 appeared in Molecules. The author of the article were Li, Hsin-Yi; Chu, Yen-Ho. The article conveys some information:
The use of affinity ionic liquids, I and II, for chemoselective detection of amine and alc. gases on a quartz crystal microbalance (QCM) was reported. These detections of gaseous amines and alcs. were achieved by nucleophilic aromatic substitution reactions with the electrophilic 1,3,5-triazine-based affinity ionic liquids, I thin-coated on quartz chips. Starting with inexpensive reagents, bicyclic imidazolium ionic liquids, I and II were readily synthesized in six and four synthetic steps with high isolated yields: 51% and 63%, resp. The QCM platform developed in this work was readily applicable and highly sensitive to low mol. weight amine gases: for isobutylamine gas (a bacterial volatile) at 10 Hz decrease in resonance frequency (i.e., ΔF = -10 Hz), the detectability using affinity ionic liquids, I was 6.3 ppb. Our preliminary investigation on detection of the much less nucleophilic alc. gas by affinity ionic liquids, I was also promising. To our knowledge, no example to date of reports based on nucleophilic aromatic substitution reactions demonstrating sensitive gas detection in these triazine ionic liquids on a QCM was reported. The results came from multiple reactions, including the reaction of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6Quality Control of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate)
tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6) belongs to ethers. Ethers lack the hydroxyl groups of alcohols. Quality Control of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other.
