Anwendungen

Pentafluorobenzaldehyde was used as derivatization reagent in a study to develop a sensitive method for the determination of primary amines in sewage sludge by headspace solid-phase micro extraction and gas chromatography-tandem mass spectrometry. It was used in the synthesis of novel, high molecular weight fluorinated aromatic polymers.

Bemerkungen

Store in a cool, dry conditions in a well sealed container. Incompatible with oxidizing agent, air, bases.
