Toxicity of Azo Dyes in Pharmaceutical Industry

Toxicity of Azo Dyes in Pharmaceutical Industry

Azo compounds represent about two thirds of all synthetic dyes. Their usage in pharmaceutical industry has many purposes. One of the most important is coloring of pharmaceutical agents which improves their easy identification. Azo dyes often used in manufacturing of pharmaceuticals are: E102 Tartrazine, E110 Sunset Yellow FCF, Ponceau 4R (Cochineal Red A), Azorubine (Carmoisine), Amaranth, E133 Brilliant Blue and E129 Allura Red. Many azo dyes show carcinogenic and mutagenic activity, and they can provoke allergic reactions. Generally, toxicity of ingredients grows with the increase of benzene rings in their structure. Carcinogenicity of azo dyes directly depends on the structure of molec ...

Know All About Solvents

Know All About Solvents

The Different Types of Solvents There are different types of solvents in organic chemistry that can effect on nucleophilic substitution reactions. We know that polar dissolves polar and nonpolar dissolves nonpolar. There are three types of solvents in organic chemistry; non-polar solvents, polar protic solvents, and polar aprotic solvents. We have two common non-polar solvents called heptane and cyclohexane. What we find in organic chemistry is non-polar solvents are not very good for most substitution reactions. The next type of the solvent is polar protic solvents. Polar protic solvents include methanol, ethanol, water, amine, and carboxylic acid. What we find with all these solvent ...

Petrochemical Industry

Petrochemical Industry

Petrochemicals In the basic sense, petrochemicals are chemical goods derived from petroleum. Some chemical compounds can also be created from other fossil fuels such as natural gas, coal and renewable resources like corn, sugarcane and more. The biggest petrochemical industries are in the United States, western European countries and of course Middle East and Asian countries like Iran. Two main types of petrochemicals The two general classes of petrochemicals are olefins and aromatics. Olefins are unsaturated hydrocarbons meaning that they only contain hydrogen and carbon atoms and have at least one double or triple bond in their structure. They are used in the basis for the poly ...

Know All About Aluminum Powder

Know All About Aluminum Powder

Aluminum Element Aluminum is everywhere. It is the third most frequent chemical element on the earth and we can find it in almost everything we use every day. It is in the cars we drive, it is in the computers we work with and it is widely in our home appliances. 8 percent of the earth’s crust belongs to aluminum but you need to know that because of its great binding capabilities, we can’t find pure aluminum in nature commonly. While aluminum is a greatly flexible and light metal but it shows a lot of strength. Thanks to these valuable features, aluminum is a very popular metal that has a lot of use in different forms. Powdered Aluminum Aluminum powder can be made in ...
