Allgemeine Beschreibung

4-Ethylbenzaldehyde is a by-product of disinfection. Kinetic constants (KI) of 4-ethylbenzaldehyde for inhibition of the diphenolase activity of mushroom tyrosinase has been investigated.

Anwendung

4-Ethylbenzaldehyde has been used in the synthesis of 4,4′-diaminotriphenylmethanes under microwave irradiation, which is useful for parallel library syntheses.

A kinetic study of the inhibition of mushroom tyrosinase by 4-substituted benzaldehydes showed that these compounds behave as classical competitive inhibitors, inhibiting the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) by mushroom tyrosinase (o-diphenolase activity). The kinetic parameter (K(I)) characterizing this inhibition was

Disinfection of raw water is essential to the production of drinking water. However, by-products of disinfection may exert toxic effects. The potential toxic effects of two of these compounds, 4-ethylbenzaldehyde (EBA) and 2,4-difluoroaniline (DFA) were investigated using the zebrafish (Danio

Two types of chicken broth, broiler broth (BB) and native chicken broth (NCB), were used to analyse their differences in aroma by gas chromatography-olfactometry/mass spectrometry (GC-O/MS). NCB contained more complex volatiles and exhibited a richer aromatic profile compared with BB.
