For professionals involved in chemical synthesis, product development, and quality control, a thorough understanding of a compound's chemical and physical properties is fundamental. Sodium 4-Amino-1-Naphthalenesulfonate, identified by CAS 130-13-2, is a key intermediate with specific characteristics that dictate its handling, storage, and application suitability. This article provides an overview of these properties, guiding procurement managers and R&D scientists on what to expect when they buy this chemical.
Sodium 4-Amino-1-Naphthalenesulfonate, also known as Sodium Naphthionate, typically presents as a white to gray to brown crystalline powder. Its molecular formula is C10H8NNaO3S, with a molecular weight of approximately 245.23 g/mol. A significant physical characteristic is its melting point, which is reported around 280°C with decomposition. This high melting point suggests good thermal stability under typical processing conditions, provided it is not exposed to excessive heat for prolonged periods.
In terms of chemical behavior, its pH in an aqueous solution (10g/l at 20°C) is generally between 6.8 and 7.0, indicating a near-neutral character, which is beneficial for many chemical processes. For optimal storage, it is recommended to keep the material below +30°C in a tightly closed container to maintain its integrity and prevent degradation. Understanding these properties is crucial for anyone looking to source this compound from a reliable manufacturer in China or elsewhere.
The synthesis of Sodium 4-Amino-1-Naphthalenesulfonate often involves processes starting from naphthionic acid or 1-naphthylamine. Its preparation methods are well-established, ensuring consistent quality from reputable suppliers. When sourcing this chemical, it’s important to consider the purity requirements for your specific application, whether it's for dye manufacturing or analytical purposes. Information on density (around 1.6703) and solubility characteristics should also be reviewed based on your process needs.
For companies seeking to purchase Sodium 4-Amino-1-Naphthalenesulfonate, consulting with experienced chemical suppliers is advisable. They can provide detailed technical data sheets and assist in selecting the appropriate grade. If you are looking for a reliable source of this compound, consider reaching out to us for a quote.
