Descrizione

Descrizione generale

Butyraldehyde (BA) belongs to the class of volatile organic compounds (VOCs).

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Applicazioni

BA has been used as an analytical reference standard for the analysis of BA in:

• Air samples by pentafluorophenyl hydrazine derivatization followed by analysis using gas chromatography (GC) equipped with flame ionization detector (FID).
• Ambient air by GC coupled to mass spectrometry (MS).

It may be used as an analytical reference standard for the analysis of BA in:

• Environmental samples by 2,4-dinitrophenylhydrazine derivatization followed by analysis using rapid resolution liquid chromatography-ultraviolet diode array detector (RRLC-UV-DAD) and RRLC coupled to ion-trap mass spectrometer (IT-MS) operating under the atmospheric pressure chemical ionization (APCI) mode.
• Saliva samples by magnetic-stirring-assisted micro-solid-phase extraction (μ-SPE) and headspace GC combined with ion-mobility spectrometry (IMS).
