FAQ
Is 2,7-naphthalenedisulfonic acid, 5-((4-chloro-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-4-hydroxy-3-((2-sulfophenyl)azo)-, trisodium salt flammable?+
2,7-naphthalenedisulfonic acid, 5-((4-chloro-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-4-hydroxy-3-((2-sulfophenyl)azo)-, trisodium salt (CAS 23211-47-4) 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 2,7-naphthalenedisulfonic acid, 5-((4-chloro-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-4-hydroxy-3-((2-sulfophenyl)azo)-, trisodium salt?+
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 2,7-naphthalenedisulfonic acid, 5-((4-chloro-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-4-hydroxy-3-((2-sulfophenyl)azo)-, trisodium salt be stored?+
Store 2,7-naphthalenedisulfonic acid, 5-((4-chloro-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-4-hydroxy-3-((2-sulfophenyl)azo)-, trisodium salt (CAS 23211-47-4) in tightly closed original containers, in a cool, dry, well-ventilated area away from incompatible materials.
Is 2,7-naphthalenedisulfonic acid, 5-((4-chloro-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-4-hydroxy-3-((2-sulfophenyl)azo)-, trisodium salt dangerous for the environment?+
No specific environmental pictogram (GHS09) is listed in our records for 2,7-naphthalenedisulfonic acid, 5-((4-chloro-6-(phenylamino)-1,3,5-triazin-2-yl)amino)-4-hydroxy-3-((2-sulfophenyl)azo)-, trisodium salt, but any chemical waste should be handled through your site's hazardous-waste procedure, not poured down the drain.
