Determination of primary and secondary aliphatic amines in the environment as sulfonamide derivatives by gas chromatography-mass spectrometry was written by Terashi, Akiko;Hanada, Yoshifumi;Kido, Azuma;Shinohara, Ryota. And the article was included in Journal of Chromatography in 1990.COA of Formula: C9H13NO2S This article mentions the following:
A gas chromatog.-mass spectrometric (GC-MS) method for the determination of primary and secondary aliphatic amines in water and sediment was developed. A standard solution of amines was added to river water, seawater, or sea sediment, and distilled under alk. conditions. The distillate was reacted with benzesulfonyl chloride to form the corresponding sulfonamides. After extracting the derivatives into CH2Cl2, the organic layer was concentrated to a definite volume The determination was carried out by GC-MS with selected-ion monitoring. The detection limits of amines in water and sediment were 0.02-2 μg/L and 0.5-50 μg/kg, resp. The recoveries were 68.4-98.8%. In the experiment, the researchers used many compounds, for example, N-Isopropylbenzenesulfonamide (cas: 5339-69-5COA of Formula: C9H13NO2S).
N-Isopropylbenzenesulfonamide (cas: 5339-69-5) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.COA of Formula: C9H13NO2S
