Product name: Cyclopentadienylmolybdenum (V) tetrachloride

Subacute to chronic toxicity:
Corrosive materials are acutely destructive to the respiratory tract,
eyes, skin and digestive tract. Eye contact may result in permanent
damage and complete vision loss. Inhalation may result in respiratory
effects such as inflammation, edema, and chemical pneumonitis. May cause
coughing, wheezing, laryngitis, shortness of breath, headache, nausea and
vomiting. Ingestion may cause damage to the mouth, throat and esophagus.
May cause skin burns or irritation depending on the severity of the
exposure.
Additional toxicological information:
Swallowing will lead to a strong corrosive effect on mouth and throat and
to the danger of perforation of esophagus and stomach.
To the best of our knowledge the acute and chronic toxicity of this
substance is not fully known.
No classification data on carcinogenic properties of this material is
available from the EPA, IARC, NTP, OSHA or ACGIH.
