2-METHYL-5-NITROPHENOL
General Information
Chemical Structure
Basic Details
Physical Properties
Applications & Grade
2-Methyl-5-Nitrophenol is a specialty intermediate primarily used in the synthesis of other key components for permanent hair coloring formulations.
- It serves as a crucial precursor for the production of 2-Methyl-5-aminophenol (also known as 5-Amino-2-methylphenol or 4-Amino-2-hydroxytoluene).
- 2-Methyl-5-aminophenol is a widely used secondary intermediate (coupler) in oxidative hair dyes. It reacts with primary intermediates and hydrogen peroxide inside the hair shaft to form larger, colored molecules that become trapped, providing long-lasting color.
- This process allows for a wide range of permanent hair colors, offering excellent gray coverage and color durability.
Our 2-Methyl-5-Nitrophenol is available in a specialized grade suitable for its intended application.
- **Cosmetics Grade:** Produced and tested to meet the high purity and quality standards required for use as an intermediate in cosmetic products, specifically hair dyes.
