FAQ
Is Tert-butyl peroxyisopropyl carbonate flammable?+
Yes. Tert-butyl peroxyisopropyl carbonate (CAS 2372-21-6) carries the GHS02 flame pictogram. Keep it away from ignition sources, use non-sparking tools, and ground metal containers when transferring liquid.
What PPE should I wear when handling Tert-butyl peroxyisopropyl carbonate?+
Chemical-splash goggles and a faceshield, chemical-resistant gloves (nitrile or butyl) and an apron are the minimum. Ventilation should be sufficient to keep vapours below the occupational exposure limit. Check SDS section 8 for material-specific breakthrough times.
How should Tert-butyl peroxyisopropyl carbonate be stored?+
Store Tert-butyl peroxyisopropyl carbonate (CAS 2372-21-6) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials. Use a flammable-liquid cabinet and keep away from oxidizers and heat. Segregate acids from bases and keep away from metals that can be attacked.
Is Tert-butyl peroxyisopropyl carbonate dangerous for the environment?+
Yes. Tert-butyl peroxyisopropyl carbonate carries the GHS09 environment pictogram. Do not release to drains, soil or waterways; collect residues for hazardous-waste disposal in line with local regulations.
Where can I find the official Safety Data Sheet for Tert-butyl peroxyisopropyl carbonate?+
Official, up-to-date SDS documents are published by each manufacturer (Sigma-Aldrich, Merck, Thermo Fisher, VWR, Carl Roth, etc.) and by regulators such as ECHA and NIOSH. This page is an educational summary and does not replace the manufacturer's SDS.
