FAQ
Is Isoamyl propionate flammable?+
Yes. Isoamyl propionate (CAS 105-68-0) 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 Isoamyl propionate?+
Safety glasses with side shields and nitrile gloves are the baseline. Ventilation should be sufficient to keep vapours below the occupational exposure limit. Check SDS section 8 for material-specific breakthrough times.
How should Isoamyl propionate be stored?+
Store Isoamyl propionate (CAS 105-68-0) 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.
Is Isoamyl propionate dangerous for the environment?+
No specific environmental pictogram (GHS09) is listed in our records for Isoamyl propionate, but any chemical waste should be handled through your site's hazardous-waste procedure, not poured down the drain.
Where can I find the official Safety Data Sheet for Isoamyl propionate?+
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.
