3-Aminophenol Hemisulfate

Product Overview

3-Aminophenol Hemisulfate is a critical organic intermediate widely utilized in the cosmetic and personal care industries, specifically for the synthesis of oxidative hair dyes. As a sulfate salt of 3-aminophenol, this compound offers enhanced stability and solubility compared to its free base form, making it an ideal choice for large-scale manufacturing processes. Our product is synthesized under stringent quality management systems to ensure consistent performance in downstream applications.

The chemical structure features an amino group and a hydroxyl group on the benzene ring, which facilitates coupling reactions with various developers to produce a wide spectrum of hair color shades. This versatility makes it a staple raw material for formulators seeking reliable and vibrant color results.

Key Specifications

Quality consistency is paramount in chemical manufacturing. We maintain tight control over physical and chemical parameters to meet international standards. The following table outlines the typical specifications for our commercial grade 3-Aminophenol Hemisulfate:

Industrial Applications

The primary application of this material is as a coupler in permanent hair coloring products. It reacts with primary intermediates in the presence of an oxidizing agent to form indole dyes within the hair shaft. Low iron content is particularly crucial in this application, as metal impurities can cause unwanted color shifts or instability in the final formulation. Our manufacturing process includes specialized purification steps to minimize metal contamination, ensuring the final hair dye product remains stable throughout its shelf life.

Beyond cosmetics, this compound serves as a versatile building block in organic synthesis for pharmaceuticals and agrochemicals, where high purity aminophenol derivatives are required. The hemisulfate form provides handling advantages, reducing dust exposure and improving workflow safety in production facilities.

Quality Assurance and Packaging

Every batch undergoes rigorous testing via High-Performance Liquid Chromatography (HPLC) and atomic absorption spectroscopy for metal content. We provide a comprehensive Certificate of Analysis (COA) with each shipment, detailing all test results against our specification limits. Our facility adheres to global safety and environmental regulations, ensuring sustainable production practices.

Standard packaging consists of 25 kg fiber drums lined with polyethylene bags to protect against moisture and contamination. Custom packaging solutions are available upon request to suit specific logistical requirements. For storage, we recommend keeping the material in a cool, ventilated area away from direct sunlight and oxidizing agents to maintain optimal quality over time.
