The 2,4,6-Trinitrobenzenesulfonic Acid, with the CAS registry number 2508-19-2, is also known as Trinitrobenzenesulfonic acid;2,4,6-
Dinitrobenzenesulfonate;2,4,6-Trinitrobenzene-1-sulfonic acid;2,4,6-Trinitrobenzenesulfonic acid.It belongs to the product categories of Combinatorial Chemistry;Detection of Amines for Primary Amines;Synthetic Organic Chemistry.Its EINECS number is 219-717-7. What's more,Its systematic name is 2,4,6-Trinitrobenzenesulfonic Acid.It is a reagent that is used to neutralize peptide terminal amino groups.The 2,4,6-Trinitrobenzenesulfonic Acid is soluble in water. Solution exhibits a strong acidic reaction.A detonating explosive substance derived from an organic sulfonic acid. Primary hazard is blast of an instantaneous explosion, not flying projectiles or fragments. Under prolonged exposure to fire or heat the containers may explode violently.

2,4,6-Trinitrobenzenesulfonic acid is a nitroaryl oxidizing acid. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
