Description

6-Amino-m-Xylene-4-Sulphonic Acid is a key aromatic sulfonic acid derivative used as a versatile chemical intermediate. Its primary value lies in its bifunctional nature, containing both an amino group and a sulfonic acid group, which makes it a crucial building block for synthesizing more complex molecules. This compound is essential for manufacturers in the dye and pigment, pharmaceutical, and agrochemical industries seeking to develop specialized products.

Application

• Dye and Pigment Intermediate: A critical precursor in the synthesis of azo dyes, acid dyes, and reactive dyes, contributing to color fastness and solubility.
• Pharmaceutical Synthesis: Serves as a building block for active pharmaceutical ingredients (APIs) and fine chemicals, leveraging its sulfonic acid group for solubility enhancement.
• Agrochemical Production: Used in the manufacture of herbicides, pesticides, and plant growth regulators where its aromatic structure is incorporated into the final molecule.
• Chemical Research & Development: Employed as a standard or starting material in organic synthesis and catalysis research within R&D laboratories.
• Surfactant and Detergent Industry: Can be utilized to produce specialized surfactants and emulsifiers due to the presence of the hydrophilic sulfonic acid group.
• Photographic Chemicals: Finds application as a component in certain photographic developers and other light-sensitive chemical formulations.

Quality Control

Our 6-Amino-m-Xylene-4-Sulphonic Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for industrial and fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
