Product Description

What is Butyronitrile?

Butyronitrile is a straight-chain aliphatic nitrile — a four-carbon chain terminating in a nitrile (cyano) group. Its polar-aprotic character and moderate boiling point make it a useful solvent in specialty electrochemical formulations, and it’s been used as a model compound in fundamental studies of vapor-deposited molecular glasses and high-temperature reaction kinetics.

Uses of Butyronitrile

Butyronitrile’s most notable manufacturing application is as an electrolyte-solvent component in dye-sensitized solar cell formulations, where its properties support efficient ion transport. It’s also used as a general organic synthesis solvent, and has been studied in high-temperature, high-pressure water hydrolysis research relevant to green-chemistry and supercritical-fluid process development.

FAQs: Butyronitrile

Mainly as an electrolyte-solvent component in dye-sensitized solar cell manufacturing, and as a general organic synthesis solvent.

Extremely — it's classified Danger and carries an H330 hazard statement, meaning it can be fatal if inhaled, in addition to being highly flammable and toxic via oral/dermal exposure. Use only in a fume hood with full respiratory protection.

This is a medical emergency given its H330 classification — follow your facility's emergency response and medical procedures immediately; move to fresh air and seek medical attention.
