Aplicação
Phthaldialdehyde has been used:
-
in the preparation of O-phthaldialdehyde reagent for analysing gentamycin content[1]
-
in the preparation of reagent for determining the degree of hydrolysis of milk proteins[2]
-
in the measurement of free amino acids of milk samples by O-phthaldialdehyde/N-acetyl-L-cysteine (OPA/NAC) assay[3]
-
in the derivatization of putrescine samples[4]
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.
