Usage

General Description

2,4-Dimercapto-5,6-diaminopyrimidine is a chemical compound that is used as an anti-dandruff agent in some cosmetic and personal care products. It is known for its ability to effectively control dandruff by targeting the fungus Malassezia furfur, which is one of the main causes of the condition. The compound is often used in shampoos and scalp treatments to help reduce flaking and itching associated with dandruff. It works by interfering with the growth and reproduction of the fungus, ultimately helping to improve scalp health and reduce the symptoms of dandruff. Additionally, it is known for its low toxicity and minimal side effects, making it a safe and effective option for controlling dandruff.

N-Alkylation of 2,6-dichloropurine hydrochloride with a variety of alcohols over alumina catalyst

2,6-Dichloropurine hydrochloride reacts with various types of alcohols using different alumina catalysts and converts into its N-9-alkyl-2-chloro-6- hydroxy-9H-purine products to an extent of 49-74%. The product selectivity depends on the stability of carbocation generated from the alcohol. More stable carbocation formulates both N-7 and N-9-alkyl-2,6-dichloropurine products, whereas the less stable carbocation results in exclusively N-9-alkyl-2-chloro-6- hydroxy-9H-purine. The catalytic activity of alumina prepared using the sol-gel method has larger Brunauer, Emmett, and Teller (BET) surface area and hence shows significantly greater catalytic activity than the commercially available alumina samples.
