Application

ECH has been used as a reference standard for the identification of ECH in epoxy-coated cans by oxolane derivatization and gas chromatography−mass spectrometry (GC-MS) in selected ion monitoring (SIM) mode and in drinking water by static headspace (HS) and purge and trap (P&T) coupled to GC equipped with an electron capture detector (GC-ECD).
It may be used as a reference standard for the analysis of (±)-ECH in drinking water by ion chromatography and in effluent water from wastewater treatment plants by HS-solid phase microextraction (HS-SPME) combined with GC-flame ionization detector (GC-FID) and GC-ECD.

General description

Epichlorohydrin (ECH) is a colorless, volatile and highly reactive organic compound which is utilized as a precursor in the production of glycerol, plastics, drugs and paints.
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

The diverse biological effects of xenoestrogens may be explained by their ability to differentially recruit co-regulatory proteins to the estrogen receptor (ER). We employed high-throughput receptor affinity binding and co-regulatory protein recruitment screening assays based on fluorescence polarization and time
