Application

Phthaldialdehyde has been used:in the preparation of O-phthaldialdehyde reagent for analysing gentamycin contentin the preparation of reagent for determining the degree of hydrolysis of milk proteinsin the measurement of free amino acids of milk samples by O-phthaldialdehyde/N-acetyl-L-cysteine (OPA/NAC) assayin the derivatization of putrescine samples

Biochem/physiol Actions

Phthaldialdehyde can be used for the pre-column derivatization of amino acids for high-performance liquid chromatography (HPLC) separation. It may also be used for flow cytometric measurements of protein thiol groups.
