FAQ
Is Bromoform flammable?+
Bromoform (CAS 75-25-2) does not carry the GHS02 flame pictogram in our records. Always confirm with the manufacturer's SDS section 9 (flash point) before assuming a product is non-flammable.
What PPE should I wear when handling Bromoform?+
Safety glasses with side shields and nitrile gloves are the baseline. Work inside a fume hood or use a suitable respirator. Check SDS section 8 for material-specific breakthrough times.
How should Bromoform be stored?+
Store Bromoform (CAS 75-25-2) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials.
Is Bromoform dangerous for the environment?+
Yes. Bromoform 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 Bromoform?+
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.
