For procurement managers, R&D scientists, and formulators in the chemical, pharmaceutical, and cosmetic industries, a thorough understanding of a compound's properties is essential before making a purchase. Oxyquinoline Sulfate, identified by CAS number 134-31-6, is a chemical substance that demands attention due to its distinct characteristics and wide-ranging applications. This article delves into the key specifications and chemical properties that define this versatile compound, aiming to guide potential buyers in their sourcing decisions.

The most commonly cited appearance for Oxyquinoline Sulfate is a yellow or pale yellow crystalline powder. This physical form is crucial for handling, storage, and integration into various manufacturing processes. Its purity is a critical specification, with most suppliers offering a minimum assay of 99.0%. This high purity level is particularly important for applications in the pharmaceutical and cosmetic sectors, where trace impurities can have significant impacts on product safety and efficacy. Buyers often search for high purity Oxyquinoline Sulfate 99% when seeking materials for sensitive formulations.

Solubility is another key characteristic that dictates how a chemical can be used. Oxyquinoline Sulfate exhibits good solubility in water, which is a significant advantage for many aqueous-based formulations, including disinfectants and some pharmaceutical preparations. It is described as slow-soluble in ethanol and insoluble in ether, providing formulators with specific guidance on suitable solvents and potential incompatibilities. Understanding these solubility profiles helps in selecting appropriate processing techniques and formulating stable products.

The chemical structure, represented by the molecular formula (C9H7NO)2.H2SO4, reveals its nature as a salt formed from 8-hydroxyquinoline and sulfuric acid. This structure contributes to its functionality as both a metal chelating agent and an antimicrobial. The melting point is typically specified between 175.0-177.0°C, offering a benchmark for thermal stability. Furthermore, the pH of a 5% aqueous solution is around 3, indicating its acidic nature when dissolved in water.

For bulk purchasing, specifications such as Residue on Ignition (typically 0.10% max.) and hygroscopicity are also important considerations. As a hygroscopic substance, proper storage in sealed containers is necessary to maintain its quality and prevent moisture absorption. When looking to buy Oxyquinoline Sulfate, procurement professionals should pay close attention to these technical details. Engaging with a reputable Oxyquinoline Sulfate manufacturer in China allows for direct access to comprehensive technical data sheets and expert advice, ensuring that the purchased chemical meets all specified requirements for your intended application.
