About HYDROQUINONE: Hydroquinone is an aromatic organic compound. In the United States, Hydroquinone may be used as an active ingredient in OTC drug products. When used as an active drug ingredient, the established name is Hydroquinone.
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C6H4(OH)2. It has two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid. Substituted derivatives of this parent compound are also referred to as hydroquinones. The name "hydroquinone" was coined by Friedrich Wöhler in 1843.

Roles Classification

Chemical Role(s):antioxidant
A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.

Biological Role(s):carcinogenic agent
A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
Escherichia coli metabolite
Any bacterial metabolite produced during a metabolic reaction in Escherichia coli.
human xenobiotic metabolite
Any human metabolite produced by metabolism of a xenobiotic compound in humans.
mouse metabolite
Any mammalian metabolite produced during a metabolic reaction in a mouse (Mus musculus).
An organic molecule or ion (usually a metal ion) that is required by an enzyme for its activity. It may be attached either loosely (coenzyme) or tightly (prosthetic group).

Application(s):skin lightening agent
Any cosmetic used to lighten the colour of skin by reducing the concentration of melanin.

Hydroquinone has a variety of uses principally associated with its action as a reducing agent that is soluble in water. It is a major component in most black and white photographic developers for film and paper where, with the compound metol, it reduces silver halides to elemental silver.
There are various other uses associated with its reducing power. As a polymerization inhibitor, hydroquinone prevents polymerization of acrylic acid, methyl methacrylate, cyanoacrylate, and other monomers that are susceptible to radical-initiated polymerization. This application exploits the antioxidant properties of hydroquinone.
Hydroquinone can undergo mild oxidation to convert to the compound parabenzoquinone, C6H4O2, often called p-quinone or simply quinone. Reduction of quinone reverses this reaction back to hydroquinone. Some biochemical compounds in nature have this sort of hydroquinone or quinone section in their structures, such as Coenzyme Q, and can undergo similar redox interconversions.
Hydroquinone can lose a proton from both hydroxyl groups to form a diphenolate ion. The disodium diphenolate salt of hydroquinone is used as an alternating comonomer unit in the production of the polymer PEEK.
Skin depigmentation

Common side effects of hydroquinone include:

Mild skin irritation and sensitization (burning, stinging)
Inflammatory reaction

HİDROKİNON Hakkında: Hidrokinon aromatik bir organik bileşiktir. Amerika Birleşik Devletleri'nde, hidrokinon OTC ilaç ürünlerinde aktif bir bileşen olarak kullanılabilir. Aktif bir ilaç bileşeni olarak kullanıldığında, isminin adı Hidrokinon'dur.
Benzen-1,4-diol veya kinol olarak da bilinen hidrokinon, C6H4 (OH) 2 kimyasal formülüne sahip olan bir benzen türevi olan bir fenol tipi olan aromatik bir organik bileşiktir.

Hidrokinon temel olarak suda çözünür bir indirgeyici madde olarak etkisiyle ilişkili çeşitli kullanımlara sahiptir. Film ve kağıt için çoğu siyah-beyaz fotoğraf geliştiricisinde, bileşik metol ile gümüş halojenürleri elementel gümüşe indirgeyen temel bir bileşendir.
İndirgeme gücüyle ilgili çeşitli başka kullanımlar da vardır. Bir polimerizasyon inhibitörü olarak, hidrokinon, akrilik asidin, metil metakrilatın, siyanoakrilatın ve radikal-başlatılmış polimerizasyona duyarlı diğer monomerlerin polimerizasyonunu önler. Bu uygulama, hidrokinonun antioksidan özelliklerini kullanır.
Hidrokinon, genellikle p-kinon veya basitçe kinon olarak adlandırılan bileşik parabenzoquinone, C6H4O2'ye dönüştürmek için hafif oksidasyona maruz kalabilir. Kinonun azaltılması bu reaksiyonu hidrokinona geri döndürür. Doğadaki bazı biyokimyasal bileşikler, Koenzim Q gibi yapılarında bu tür bir hidrokinon veya kinon kesite sahiptir ve benzer redoks dönüşümlerine maruz kalabilirler.
Hidrokinon, bir difenolat iyonu oluşturmak için her iki hidroksil grubundan bir proton kaybedebilir. Hidrokinonun disodyum difenolat tuzu, PEEK polimerinin üretiminde alternatif bir komonomer birimi olarak kullanılır.
Cilt depigmentasyonu

Hidrokinonun ortak yan etkileri şunlardır:

Hafif cilt tahrişi ve hassaslaşması (yanma, yanma)
İnflamatuar reaksiyon
