For professionals involved in chemical synthesis, quality control, and material science, a thorough understanding of chemical properties and safe handling procedures is essential. 1-Amino-2-Naphthol-4-Sulfonic Acid (CAS 116-63-2) is a versatile compound primarily used as a dye intermediate, and knowing its characteristics is key to its effective and safe utilization. As a dedicated manufacturer and supplier, we provide insights into the properties and handling of this important chemical.

Physical Appearance and Solubility: 1-Amino-2-Naphthol-4-Sulfonic Acid is typically supplied as a white to light pink powder. Its solubility profile is important for application. While it is described as insoluble in cold water, ethanol, ether, and benzene, it shows solubility in hot water, hot sodium bisulfite solutions, and alkali solutions. This characteristic is fundamental when designing reaction or purification protocols. For researchers or formulators looking to buy 1-Amino-2-Naphthol-4-Sulfonic Acid, this solubility behavior dictates appropriate solvent choices.

Chemical Structure and Reactivity: With the molecular formula C10H9NO4S and a molecular weight of 239.25, this compound features an amino group (-NH2), a hydroxyl group (-OH), and a sulfonic acid group (-SO3H) attached to a naphthalene ring system. These functional groups dictate its reactivity. The amino and hydroxyl groups are crucial for diazotization and coupling reactions in dye synthesis, while the sulfonic acid group imparts water solubility and influences its behavior in various chemical environments. It is stable under recommended storage conditions but can react with strong oxidizing agents.

Safe Handling and Storage: Adhering to safety guidelines is paramount when working with any chemical. 1-Amino-2-Naphthol-4-Sulfonic Acid is classified with hazard statements indicating it may cause skin irritation (H315), serious eye irritation (H319), and respiratory irritation (H335). Therefore, appropriate personal protective equipment (PPE), including gloves, eye protection, and respiratory protection, should be used when handling. It should be stored in a cool, dry, and well-ventilated place, away from incompatible materials such as strong bases and oxidizing agents. Our packaging, typically 25kg drums, is designed for safe transport and storage. As a responsible supplier, we ensure that Safety Data Sheets (SDS) are readily available for detailed safety information.

Quality Assurance for Industrial Use: For industrial applications, especially in dye manufacturing, maintaining product integrity is essential. Our manufacturing processes ensure that the 1-Amino-2-Naphthol-4-Sulfonic Acid we supply adheres to strict quality standards, including a minimum purity of 98.0%. This consistency is vital for achieving predictable results in complex chemical reactions.
