11 Toxicological information
Acute toxicity:
Primary irritant effect:
on the skin: Irritant to skin and mucous membranes.
on the eye: Irritating effect.
Sensitization: No sensitizing effects known.
Subacute to chronic toxicity:
Uranium compounds may cause skin, eye or lung irritation. Cancers of the
liver, kidney, lymphatic and blood forming tissues are possible.
Necrotic arterial lesions are possible.
Subacute to chronic toxicity:
2,4-Pentanedione (acetylacetone), if present or released, is harmful if
swallowed, irritates the skin, and severely irritates the eyes. 2,4-
Pentanedione has caused mutagenic and reproductive effects in laboratory
animals and is also flammable. No information is known about the amount
of free 2,4-pentanedione present in or released by this compound.
Additional toxicological information:
To the best of our knowledge the acute and chronic toxicity of this
substance is not fully known.
ACGIH A1: Confirmed human carcinogen: Agent is carcinogenic to humans
based on epidemiologic studies of, or convincing clinical evidence in,
exposed humans.
