Ethylparaben is the ethyl ester of p-hydroxybenzoic acid. Its formula is HO-C6H4-CO-O-CH2CH3. It is a member of the class of compounds known as parabens. Ethyl 4-hydroxybenzoate, 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.
E 1580 (OTTO) Ethyl p-hydroxybenzoate, 99% Cas 120-47-8 - used to study the in-situ derivatisation solid-phase microextraction procedure for determining parabens, related chlorophenols, and triclosan in water.
