Toxicity Summary

IDENTIFICATION AND USE: Antimony pentafluoride is a hygroscopic, viscous liquid. It is used in the fluorination of organic compounds. HUMAN STUDIES: It is a corrosive liquid to skin, eyes, mucous membranes. ANIMAL STUDIES: Distribution in rats after chronic poisoning by inhalation of antimony pentafluoride showed high antimony concentration in blood. Levels in liver, kidneys, spleen and pancreas were similar. The antimony was retained for a long time and could be detected in organs under examination one month after experiment discontinued.

Human Toxicity Excerpts

/SIGNS AND SYMPTOMS/ A very reactive, corrosive liquid to skin, eyes, mucous membranes.

Evidence for Carcinogenicity

A4; Not classifiable as a human carcinogen. /Fluorides, as F/
