Description

General description

Propionaldehyde is a volatile organic compound, which belongs to the class of flavor & fragrance standards for use in the food, beverage and cosmetic industry. These standards are widely used to add taste and/or smell to products without aroma, to mask unpleasant odors and to maintain stability of original flavor.

Application

Propionaldehyde may be used as an analytical reference standard for the quantification of the analyte in:
• Food products and cosmetics using gas-chromatography with photo ionization detection (GC-PID).
• Infant formulas using gas chromatography with flame ionization detection (GC-FID).
• Household products using gas chromatography coupled to mass spectrometry (GC-MS).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
