Uses and synthesis of Monobenzone powder

Monobenzone powder is a topical depigmenting agent used for the treatment of hyperpigmentation, such as various pigmentation spots, age spots, melanoma, etc. It is very effective.

Monobenzone CAS 103-16-2 can decompose melanin in the skin, prevent the production of melanin in the skin, so that the skin to restore healthy colour, but does not destroy the melanocytes, toxicity is very light, Monobenzone Raw Materials are usually made into ointment or application, has been included in the U.S. Pharmacopoeia, our country has not been produced!

Applications / Functions of Monobenzone powder

Used as pharmaceutical intermediates

• Monobenzone powder is a topical depigmenting agent used for the treatment of hyperpigmentation, such as various pigmentation spots, age spots, melanoma, etc. The effect is very obvious.
• Monobenzone Raw Materials can decompose melanin in the skin, prevent the production of melanin in the skin, so that the skin to restore healthy colour without destroying the melanocytes, the toxicity is very light, usually made into ointment or application, and it can be used in the treatment of hyperpigmentation, such as various kinds of pigmentation, age spots, melanoma, etc. The effect is obvious.

Physicochemical Property of Monobenzone powder

Monobenzone CAS 103-16-2 is a colourless solid, classified as hydroquinone monobenzyl ether. Monobenzone is soluble in alcohol, benzene, and ether, and practically insoluble in water.

Monobenzone powder is a decolourising agent with the effect of enhancing the rate of elimination of melanin secreted by skin cells, and studies have shown that the molecular mechanism of its action may be related to tyrosinase.

Production methodprocess of Monobenzone powder

Add 2.63g (0.028mol) of hydroquinone in a 100mL conical flask, weigh 1.12g (0.028mol) of sodium hydroxide, add 8mL of water, wait for the sodium hydroxide to be dissolved and then added dropwise to the conical flask containing hydroquinone, shaken thoroughly, then add 15mL of LDMF and 2.52g (0.02mol) of benzyl chloride, and then add 15mLDMF and 2.52g (0.02mol) of benzyl chloride, then add 15mLDMF and 2.52g (0.52mol) of benzyl chloride, and then add 15mLDMF and 2.52g (0.52mol) of benzyl chloride. Under the condition of microwave radiation power of 320W, the reaction was carried out for 60s.

After the reaction, it was cooled to room temperature. The reaction was first adjusted to alkaline with 10% sodium hydroxide, filtered, and the filtrate was washed with 10% sodium hydroxide until the filtrate was colourless (the filtrate was hydroquinone bisbenzyl ether, which could be recycled). The filtrate was acidified with hydrochloric acid to precipitate Monobenzone Raw Materials completely, then after filtration and ice water washing, recrystallised with alcohol and water, and decoloured with activated charcoal, 2.55g of white solid was obtained, with a yield of 63.79%.
