Chemical structure



Carcinogen. Toxic by inhalation, ingestion and skin absorption. Nonflammable.

Chloroform can decompose when exposed to heat, moisture and UV light forming highly toxic fumes (phosgene, chlorine gas and hydrogen chloride). Reacts violently with bases, oxidants and some metals (e.g.,aluminium, lithium, magnesium, potassium, sodium), causing fire and explosion hazard. Attacks plastic, rubber and coatings.
