Description

Aplicação

Phthaldialdehyde has been used:

• in the preparation of O-phthaldialdehyde reagent for analysing gentamycin content
• in the preparation of reagent for determining the degree of hydrolysis of milk proteins
• in the measurement of free amino acids of milk samples by O-phthaldialdehyde/N-acetyl-L-cysteine (OPA/NAC) assay
• in the derivatization of putrescine samples

Ações bioquímicas/fisiológicas

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.
