Phthalaldehyde, pale yellow crystal, sensitive to light and air, can evaporate with water vapor. Soluble in water, ethanol, ether and organic solvents, slightly soluble in petroleum ether. It's irritating. Mainly used for 1. Chemical analysis reagent: as an amine alkaloid reagent, it is used for fluorescence determination of primary amine and peptide bond decomposition. 2, organic synthesis: also is the medicine intermediate. 3. Fluorescence reagent, used for separating amino acid derivatives by HPLC before column, and flow cytometry to measure mercaptan groups of proteins.
