Description

General description

Dansyl Chloride, also known as 5-dimethylamino naphthalene-1-sulfonyl chloride, is a pre-column derivatization reagent. [1] After the derivatization reaction, the fluorescent derivatives are analyzed using several analytical methods like NMR, IR, UV-vis, and fluorescence microscopy.[2] Dansyl Chloride is a typical aromatic sulphonyl chloride that reacts with various bases, resulting in derivatives with variable stability.

Application

A fluorogenic reagent for fluorescent N-terminal derivatization of amino acids and peptides and detection by reverse phase HPLC.

Dansyl Chloride is used as a derivatization reagent to study extensive metabolism and low doses of ethinylestradiol administered during pre-clinical studies.[3] Studies conducted to determine bisphenols in human serum through the HPLC method used Dansyl Chloride to obtain the derivative products.[4] Dansyl Chloride derivatives are suitable for LC/MS determination and characterization of glyphosate, aminomethylphosphonic acid (AMPA), and glufosinate from food samples.[1]
