The molecule is a dialdehyde, consisting of two formyl (CHO) groups attached to adjacent carbon centres on a benzene ring.
o-Phthalaldehyde is used for precolumn derivatization of amino acids for HPLC separation and for flow cytometric measurements of protein thiol groups. Used for fluorometric determination of histamine, histidine and other amino acids. Also used for cholesterol assay in the picomole range.
