Description

5-Amino-o-Xylene-3-Sulphonic Acid is a key aromatic sulfonic acid derivative used as a versatile intermediate in the synthesis of complex organic molecules. Its value lies in its bifunctional nature, featuring both an amino group and a sulfonic acid group, which allows for selective reactions and the introduction of water-solubilizing properties into target compounds. This chemical is primarily needed by manufacturers in the dye and pigment, pharmaceutical, and agrochemical industries for creating high-value specialty products.

Application

• Dye and Pigment Intermediate: A crucial building block for the synthesis of azo dyes, acid dyes, and reactive dyes, imparting color and specific fastness properties.
• Pharmaceutical Intermediate: Used in the production of active pharmaceutical ingredients (APIs) where the sulfonic acid group can enhance solubility and bioavailability.
• Agrochemical Synthesis: Serves as a precursor in the manufacture of certain herbicides, fungicides, and plant growth regulators.
• Chemical Research & Development: Employed as a model compound or starting material in organic synthesis for novel material discovery.
• Functional Material Production: Potential use in the synthesis of optical brighteners, liquid crystal materials, and corrosion inhibitors.

Quality Control

Our 5-Amino-o-Xylene-3-Sulphonic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet the agreed specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee full 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 after opening to prevent absorption of atmospheric moisture, which can affect product quality.
