5-Ethylidene-2-norbornene is a chemical that has been used in the past as an ingredient in plastics and rubber. It is now being investigated as a possible diagnostic agent for chronic exposure to hydrogen chloride. 5-Ethylidene-2-norbornene reacts with hydrogen chloride to form a fluorescent compound that can be detected by nmr spectroscopy. This reaction allows for the detection of hydrogen chloride at concentrations below the threshold limit value of 0.1 ppm, which is set by OSHA. The detection of hydrogen chloride can be accomplished using an optical sensor or by microencapsulating 5-ethylidene-2-norbornene inside a polymer matrix and measuring the fluorescence from the microcapsules. The use of 5-ethylidene-2-norbornene for this application is still under investigation but it may have potential clinical use as a diagnostic tool for chronic exposure to hydrogen chloride.
