4-NITROBENZENEDIAZONIUM TETRAFLUOROBORATE Chemical Properties,Usage,Production

Chemical Properties

Pale Yellow Solid

Uses

4-Nitrobenzenediazonium tetrafluoroborate is widely used as a standard reagent in organic synthesis. It is used as a dye for enterochromaffin cells. It is used for the spectrophotometric determination of common aromatic diisocyanates [toluene-2,4-diyl diisocyanate and 4,4'-methylenebis(phenyl isocyanate)] and gallic acid. It is also used for tissue staining and determination of trace phenols.

Purification Methods

It crystallises from water. [Whetsch et al. J Am Chem Soc 78 3360 1956, Beilstein 16 IV 816.] It can be EXPLOSIVE when dry.
