FAQ
Is 2-Nitrobenzenesulfonyl chloride flammable?+
2-Nitrobenzenesulfonyl chloride (CAS 1694-92-4) 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 2-Nitrobenzenesulfonyl chloride?+
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 2-Nitrobenzenesulfonyl chloride be stored?+
Store 2-Nitrobenzenesulfonyl chloride (CAS 1694-92-4) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials. Segregate acids from bases and keep away from metals that can be attacked.
Is 2-Nitrobenzenesulfonyl chloride dangerous for the environment?+
No specific environmental pictogram (GHS09) is listed in our records for 2-Nitrobenzenesulfonyl chloride, 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 2-Nitrobenzenesulfonyl chloride?+
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.
