Application
Isoamyl nitrite (CAS 110-46-3), also known as isopentyl nitrite or amyl nitrite, is a nitrite ester widely used as a pharmaceutical intermediate, organic synthesis reagent, and fine chemical. In pharmaceutical applications, it acts as a fast-acting vasodilator for the treatment of angina pectoris and hypertension, and serves as a cyanide poisoning antidote by converting hemoglobin to methemoglobin, which binds cyanide to form non‑toxic cyanmethemoglobin. In organic synthesis, isoamyl nitrite is utilized as a nitrosating agent, oxidant, and radical initiator. It is employed for the generation of benzyne from anthranilic acid, functionalization of multi‑walled carbon nanotubes, and synthesis of diazonium salts. The compound is also used in the preparation of 4-carboxy‑phenyl diazonium salt tetrafluoroborate and as a nitrosating agent for phosphoramidites. In the flavor and fragrance industry, it is an intermediate for perfume preparation and an ingredient in room odorizers. Additional applications include its use as a solvent and chelating agent in industrial formulations.
