Chemische Eigenschaften
slightly red powder
synthetische
The preparation of 4-Hexylresorcinol involves two methods:
The reaction of caproic acid and resorcinol in the presence of a catalyst.
Reduction of hexanoylresorcinol with zinc amalgam and dilute hydrochloric acid.
Allgemeine Beschreibung
P-hexylresorcinol appears as pale-yellow viscous liquid (that becomes solid on standing at room temperature) or a peach colored powder. Pungent faintly fatty odor. Sharp astringent taste. (NTP, 1992)
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
4-Hexyl-1,3-benzenediol may be sensitive to prolonged exposure to light. Incompatible with acid chlorides, acid anhydrides and oxidizing agents .
Hazard
Irritant to respiratory tract and skin, concentrated solutions are vesicant.
Brandgefahr
Flash point data for 4-Hexyl-1,3-benzenediol are not available. 4-Hexyl-1,3-benzenediol is probably combustible.
Clinical Use
Hexylresorcinol, also known as 4-hexylresorcinol, is a white crystalline substance with a faint phenolic odor. When applied to the tongue it produces a sensation of numbness. It is freely soluble in alcohol but only slightly soluble in water(1–20,000 parts). Hexylresorcinol is an effective antiseptic,possessing both bactericidal and fungicidal properties.The phenol coefficient of hexylresorcinol against S. aureusis 98. As is typical for alkylated phenols, hexylresorcinol possesses surfactant properties. The compound also haslocal anesthetic activity. Hexylresorcinol is formulated into throat lozenges because of its local anesthetic and antisepticproperties. These preparations are probably of little value. Hexylresorcinol (in the concentration in thelozenge) is probably not antiseptic, and the local anestheticproperty can anesthetize the larynx, causing temporary laryngitis.
