A Rapid HPLC Determination of C 2 -C 7 Aliphatic Diamines by Precolumn Derivatization with Acetylacetone in Methanol-Water

Rapid Determination of 1,2-Diaminoethane and 1,6-Diaminohexane in Water by Miniature Capillary Electrophoresis

“…M. Liu and Cheng 2003;Sun et al 2003;Wang et al 2003;Chu et al 2006;Gong and Hauser 2006;Kvasnicka and Voldrich 2006;M. Li and Lee 2007;Li 2012) and derivatization approaches (Wintersteiger et al 1995;Asan and Isildak 1999;Gao et al 2011;Kang et al 2011), the LODs based on field-amplified sample injection were superior (1,2-diaminoethane: 0.013 ng=mL vs. 10 nM vs. 0.18 ng=mL; 1,6-diaminohexane: 0.11 ng=mL vs. 7.6 mM vs. 0.46 ng=mL), and the sensitivity was improved between 10 and 1000 times.…”

“…The most common method for the determination of aliphatic amines is high performance liquid chromatography (HPLC) (Ö nal 2007), using fluorescence Kang et al 2011), ultraviolet-visible (Asan andIsildak 1999;Kamarei, Ebrahimzadeh, and Asgharinezhad 2011;Moliner-Martinez, Herraez-Hernandez, and Campins-Falco 2007), and electrochemical detection (Wintersteiger et al 1995;Misiego, Gil, and Lomba 2000;Lamba et al 2008). Gas chromatography (GC) also has been employed for this analysis (Jurado-Sanchez, Ballesteros, and Gallego 2010; Singh et al 2011).…”

“…Aliphatic diamines are widely used as chemical reagents, occur as metabolites in biomedical studies, and are often used as chelating agents in analytical chemistry (Asan and Isildak 1999). Low levels of these diamines in food are not considered to be a health risk.…”

Fast Determination of Ethylendiamine in Aminophylline Tablets by Small‐sized Capillary Electrophoresis with Amperometric Detection

“…[6][7][8][9][10] High performance liquid chromatography (HPLC) [11] and gas chromatography (GC) [12,13] have been employed for the purpose. However, the above methods still have some drawbacks of low sensitivity, complicated derivatization procedures or high analytical cost.…”

Application of diethyl ethoxymethylenemalonate (DEEMM) derivatization for monitoring of lysine decarboxylase activity

“…Aliphatic diamines such as 1,3-diaminopropane (C3), 1,4-diamine (putrescine) (C4), 1,5-52 diamine (cadaverine) (C5), hexamethylenediamine (C6) and heptamethylenediamine (C7) are 53 widely used as chemical reagents in the preparation of polyamides, polyimides and polyureas 54 [1], with an additional use as chelating agents for analytical purposes [2]. They are made by 55 petroleum-based methods, and have been found to have high potential for the production of 56 polyamide, which can be made by reaction of aliphatic diamines and dicarboxylic acid [3].…”
