Description

General description

Isopentyl nitrite, also known as isoamyl nitrite, is an oxidant, and nitrosating agent for phosphoramidites which rearrange into phosphotriesters during nitrosation.

Application

Isopentyl nitrite has been used:

• as a radical initiator to functionalize multi-walled carbon nanotubes.
• as a reagent in the preparation of 4-carboxy-phenyl diazonium salt tetrafluoroborate.
• in the synthesis of peroxynitrite (ONOO-).

Isopentyl nitrite, also known as isoamyl nitrite, is used for the generation of benzyne from anthranilic acid. Its applications are also seen in kits to treat cyanide poisoning, its function being to oxidize hemoglobin (Hb) to methemoglobin (metHb) which reacts with cyanide to form the non-toxic cyano-metHb.
