FAQ
Is Benzaldehyde flammable?+
Benzaldehyde (CAS 100-52-7) 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 Benzaldehyde?+
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 Benzaldehyde be stored?+
Store Benzaldehyde (CAS 100-52-7) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials.
Is Benzaldehyde dangerous for the environment?+
No specific environmental pictogram (GHS09) is listed in our records for Benzaldehyde, 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 Benzaldehyde?+
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.
