Hazardous Substances Data	123-31-9(Hazardous Substances Data)
Toxicity	LD50 orally in rats: 320 mg/kg (Woodard)

Chemical Properties	white needle-like crystals or crystalline powder
Uses	K channel agonist, antihypertensive
Uses	Hydroquinone
Uses	reducing agent prevents polymerization of resin monomers lightens darkened skin, light sensitive
Uses	Use as photographic reducer and developer; as reagent in the determination of small quantities of phosphate; as antioxidant. Depigmentor
Definition	ChEBI: A benzenediol comprising benzene core carrying two hydroxy substituents para to each other.
Uses	As photographic reducer and developer; as reagent in the determination of small quantities of phosphate; as antioxidant.
General Description	Light colored crystals or solutions. May irritate the skin, eyes and mucous membranes. Mildly toxic by ingestion or skin absorption.
Air & Water Reactions	Darkens on exposure to air and light. Miscible in water. Solutions become brown in air due to oxidation. Oxidation is very rapid in the presence of alkali.
Reactivity Profile	Hydroquinone is a slight explosion hazard when exposed to heat. Incompatible with strong oxidizing agents. Also incompatible with bases. Hydroquinone reacts with oxygen and sodium hydroxide. Reacts with ferric salts . Hot and/or concentrated NaOH can cause Hydroquinone to decompose exothermically at elevated temperature. (NFPA Pub. 491M, 1975, 385)
Health Hazard	Hydroquinone is very toxic; the probable oral lethal dose for humans is 50-500 mg/kg, or between 1 teaspoon and 1 ounce for a 150 lb. person. It is irritating but not corrosive. Fatal human doses have ranged from 5-12 grams, but 300-500 mg have been ingested daily for 3-5 months without ill effects. Death is apparently initiated by respiratory failure or anoxia.
Fire Hazard	Dust cloud may explode if ignited in an enclosed area. Hydroquinone can react with oxidizing materials and is rapidly oxidized in the presence of alkaline materials. Oxidizes in air.
