General description

1,2-Propanediol is a compound found to be chemically similar to ethylene glycol and is widely used in automobile antifreeze, activated charcoal preparations, cosmetics, beverages, ointments, etc. It is used as a diluent for the intravenous preparations of poorly water-soluble drugs.
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

Application

1,2-Propanediol may be used as an analyte protectant for the gas chromatography-mass spectrometric detection of environmental contaminants in honey, honeybees and pollens. It is also used as an analytical reference standard for the quantification of the analyte in biological fluids using headspace-gas chromatography (HS-GC) technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
