Air & Water Reactions
Soluble in water. Solution exhibits a strong acidic reaction.
Reactivity Profile
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.
Health Hazard
Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard
MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.
Purification Methods
Recrystallise TNBS from 1M HCl, or a mixture of EtOH (50mL), H2O (30mL) and conc HCl (70mL) for 65g of acid, and dry it at 100o. The diethanolamine salt had m 182-183o [Golumbic J Org Chem 11 518 1946]. [Beilstein 11 III 161.]
Check Digit Verification of cas no
The CAS Registry Mumber 2508-19-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,0 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2508-19:
(6*2)+(5*5)+(4*0)+(3*8)+(2*1)+(1*9)=72
72 % 10 = 2
So 2508-19-2 is a valid CAS Registry Number.

, p. 4423 - 4431 (2021/04/06)
Fluoromethyl-2,4,6-trinitrophenylsulfonate has been prepared for the first time and qualified as a simple to use monofluoromethylating reagent. Its molecular structure in the solid state has been determined by single-crystal X-ray diffraction studies. This reagent proves to be effective for the electrophilic introduction of a CH2F group into selected chalcogen and nitrogen nucleophiles. Monofluoromethyl derivatives of various bifunctional N,O-nucleophiles have been synthesized using fluoromethyl-2,4,6-trinitrophenylsulfonate. Due to the good crystallizing properties of the anion, the fluoromethylated products as well as side products that are difficult to identify by nuclear magnetic resonance spectroscopy can readily be characterized by X-ray crystallographic techniques.
