General Description

Straw-yellow to green solid or liquid with a sweet, alcohol-like odor. Denser than water. Not a specific compound (alkyl refers to any of a series of organic substituents such as butyl or hexyl).

Hazards

Reactivity Alerts

none

Air & Water Reactions

No rapid reaction with air. No rapid reaction with water.

Fire Hazard

Special Hazards of Combustion Products: Irritating oxides of sulfur and phosphorus may form in fires. (USCG, 1999)

Health Hazard

(All commercially available members of this class have about the same health hazards.) Inhalation of dust can cause respiratory discomfort. Ingestion causes irritation of mouth and stomach. Contact with eyes causes moderately severe irritation. Contact with skin causes mild irritation. (USCG, 1999)

Reactivity Profile

May form highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
