Anwendungen

Ethyl 4-hydroxybenzoate (ethylparaben) was used to study the in-situderivatisation solid-phase microextraction procedure for determining parabens, related chlorophenols and triclosan in water. It is a novel sorbent for solid-phase extraction, was used to study its retention property. It has high extraction efficiency towards the compounds tested owing to the electrostatic interaction, hydrophobic interaction and hydrogen bonding.

Bemerkungen

Stable under recommended storage conditions. Incompatible with oxidizing agents.
