General Description

4-hydroxy-7-methylamino-2-Naphthanlenesulfonic acid, also known as Methyl Orange, is a synthetic compound commonly used as a pH indicator in laboratory settings. Its chemical structure consists of a naphthalene ring with a methylamino group and a hydroxy group, as well as a sulfonic acid group. Methyl Orange is commonly used in titrations to determine the endpoint of a reaction by changing color based on the pH of the solution. It is typically red in acidic conditions and yellow in alkaline conditions, making it a useful tool for determining the acidity or basicity of a solution in chemical analysis. Additionally, Methyl Orange is also used in the textile industry as a dye for silk and wool, and as a colorant in various products. However, it should be handled with care as it is toxic if ingested and can cause irritation to the skin and eyes.
