Produktinformation

• Name: 2,4,6-Trinitrobenzenesulfonic acid - 5% Aqueous solution
• Marke: Biosynth
• Beschreibung: 2,4,6-Trinitrobenzenesulfonic acid (also known as TNBS, TNSBA or picrylsulfonic acid) is a strongly oxidising organic acid that has long been used as a reagent to determine the presence of free primary amine groups. TNBS reacts rapidly with primary amines to form highly coloured N-trinitrophenyl acid products which can then be analysed by colorimetry. The amine can be regenerated by treatment with hydrazine. This analytical technique can also be applied to thiols and hydrazides.; As is common with nitrated aromatic compounds, there is a risk of explosion and TNBS is typically commercially available as a solution. We also supply the 1% solution in DMF.
