Product Information

• Name: 2,4,6-Trinitrobenzenesulfonic acid, 1% DMF solution
• Brand: Biosynth
• Description: 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 products which can then be analysed by colorimetry. Competing hydrolysis of the TNBS reagent may influence the assay result. 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 5% aqueous solution.
