(9-Anthryldiazomethane) ADAM is a highly fluorescent and ultraviolet label for spectrophotometric determination of picomole quantities of fatty acids by high-pressure liquid chromatography. It has been used to detect and quantify picomole quantities of fatty acids, carboxylic acids, prostaglandins, and urinary oxalic acid. Common fluorescent diazomethane analogue used to derivatize biomolecules. Also has been used to detect several types of acids, including amino acids, bile acids, fatty acids, prostaglandins, and steroid acids.
