CAS 78-92-2

sec-Butyl alcohol (2-Butanol)

sec-Butyl alcohol is a colorless, flammable solvent used in making paints, coatings, and methyl ethyl ketone. It matters because its vapors can irritate the eyes and airways and, at higher levels, affect the nervous system [1][2].

Where It Comes From

Industrial chemical used as a solvent and to make methyl ethyl ketone; found in some paints, inks, adhesives, and cleaners [1][3].

How You Are Exposed

Breathing vapors during work or DIY projects, skin contact with liquid, or accidental swallowing; levels can build up indoors without good ventilation [1][2].

Why It Matters

Short-term exposure can cause eye, nose, and throat irritation, headache, dizziness, and nausea; very high levels may cause drowsiness and poor coordination; liquid can dry/irritate skin [1][2].

Who Is at Risk

Workers in painting, printing, coatings, and chemical manufacturing; anyone using solvent products without ventilation; children and people with breathing problems may be more sensitive [1][2].

How to Lower Your Exposure

Choose low-VOC products; use outside or increase ventilation; keep containers closed; wear gloves and eye protection; follow label directions; store away from heat/ignition sources [1][2].
