Spectrophotometric determination of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride by flow injection analysis.
1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC.HCl) is a very useful agent to form amide bonds (peptide bonds) in an aqueous medium. A simple and fast detection system was developed using the reaction with pyridine and ethylenediamine in acidic aqueous solution and spectrophotometric flow injection analysis. The absorbances were measured at 400 nm and the reaction was accelera...
متن کاملDevelopment of Sequential Injection Analysis for Determination of 1–(3–Dimethylaminopropyl)–3–Ethylcarbodiimide Hydrochloride (EDC・HCl) Based on Condensation Reaction between Malonic Acid and Ethylenediamine
A sequential injection analysis (SIA) using a specific condensation reaction between malonic acid and ethylenediamine with 1–(3–dimethylaminopropyl)–3–ethylcarbodiimide hydrochloride (EDC・HCl) in aqueous media was developed for EDC・HCl determination. EDC・HCl can act as a dehydration or condensation reagent for the formation of amide (peptide). The proposed system, whose operation was fully auto...
متن کاملSulfuric acid {[3-(3-silicapropyl)sulfanyl]propyl}ester as a recyclable solid acid catalyst for the synthesis of α-amino nitriles
Sulfuric acid {[3-(3-silicapropyl)sulfanyl]propyl}ester (SASPSPE) is employed as a recyclable catalyst for the synthesis of α-amino nitriles. These syntheses were performed via a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide under mild reaction conditions at room temperature. The catalyst could be recycled and reused several times without any loss of effi...

متن کاملMetabolism of Indole-3-acetic Acid: IV. Biological Properties of Amino Acid Conjugates.
The biological activity of 20 l-alpha-amino acid conjugates of indole-3-acetic acid (IAA) to stimulate cell elongation of Avena sativa coleoptile sections and to stimulate growth of soybean cotyledon tissue cultures has been examined at concentrations of 10(-4) to 10(-7)m. In the Avena coleoptile test, most of the amino acid conjugates stimulated elongation. Several of the conjugates stimulated...
