Description of key information

At temperatures approching the auto flammability point, chemical decomposition will occur resulting in the potential release of gaseous H2S and other low MW mercaptan and thioethers.

Additional information

This substance is considered stable under normal ambient and anticipated storage and handling condition of temperature and pressure. This includes exposure to direct sunlight for extended periods of time and various metals and metal alloys commonly present in storage vessels. This substance is not completely stable to heating if the temperature approaches its auto flammability point, or the substance is exposed to temperatures near its flash point (while in the presence of an ignition source). At somewhat lower temperatures minor decomposition may be evident causing the release of potentially toxic H2S fumes and other low molecular weight mercaptans and thioethers.
