CAS 123-31-9: Hydroquinone

Description:Hydroquinone, with the CAS number 123-31-9, is an organic compound characterized by its aromatic structure, specifically a dihydroxybenzene derivative. It appears as a white crystalline solid and is soluble in water, alcohol, and ether. Hydroquinone is known for its reducing properties and is commonly used as a photographic developer, antioxidant in various applications, and a skin-lightening agent in cosmetics due to its ability to inhibit melanin production. It has a melting point around room temperature and exhibits a slightly sweet taste. Hydroquinone can undergo oxidation to form benzoquinone, which is a more reactive compound. While it is generally considered safe in low concentrations, prolonged exposure or high doses can lead to skin irritation and other health concerns, prompting regulatory scrutiny in some regions. Its use in cosmetic formulations is often subject to concentration limits to mitigate potential adverse effects. Overall, hydroquinone is a versatile compound with significant applications in both industrial and cosmetic fields.
