Description

General description

Bisphenol S (BPS), belonging to the class of bisphenols, is a structural analog of bisphenol A (BPA), used in a variety of industrial applications and products marketed as BPA-free. It is commonly identified in food and beverages, environmental samples, biological matrices, etc. It is also reported to be used in the production of epoxy resins. BPS is also found to be stable compared to BPA at elevated temperature and sunlight conditions.

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

Bisphenol S may be used as an analytical reference standard for the determination of the analyte in:

• Beverages using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS).
• Biological samples using high performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS).
• Environmental water samples using high performance liquid chromatography (HPLC) with ultraviolet (UV) detection.
