Description
A yellow, oily liquid with a putrid smell. Antimony pentachloride is used as a Stain for materials containing hydroxyl groups such as Dammar, Mastic, sterols, nondrying oils, and vitamins. It reacts to form an adduct that fluoresces blue-white in Ultraviolet light. Antimony pentachloride is moisture sensitive and will decompose in the presence of Water or alcohols.
