For chemists, formulators, and procurement managers in the chemical industry, a thorough understanding of a substance's chemical properties is fundamental to its successful application. Didodecyldimethylammonium Bromide (DDAB), a widely used double-chain cationic surfactant and phase transfer catalyst (CAS 3282-73-3), exhibits a distinct set of physical and chemical characteristics that dictate its behavior in various industrial processes. As a leading supplier and manufacturer, we provide insight into these critical properties.

Physically, Didodecyldimethylammonium Bromide is typically described as a light yellow solid. Its solid form at room temperature, with a reported melting point range of 157-162 °C (according to literature), makes it relatively easy to handle and store. This solid state is advantageous for packaging, shipping, and precise dosing in various formulations. The precise appearance can vary slightly depending on the purity and manufacturing batch, but it generally presents as a crystalline powder or solid mass.

In terms of solubility, DDAB demonstrates good solubility in polar organic solvents like ethanol. The provided information indicates a solubility of 0.1 g/mL in ethanol, resulting in a clear, colorless solution. While it is also soluble in water, its performance as a surfactant and phase transfer catalyst often leverages its behavior in mixed aqueous-organic systems. Its solubility profile is a key factor in its effectiveness as a phase transfer agent, allowing it to efficiently interact with both aqueous and organic reactants.

Stability is another crucial aspect of DDAB's chemical profile. The compound is generally considered stable under recommended storage conditions, typically in a cool, ventilated place, and protected from moisture and strong oxidizing agents. Hygroscopic in nature, it can absorb moisture from the air, emphasizing the need for tightly sealed containers. Understanding these stability parameters is vital for ensuring the longevity and efficacy of DDAB when stored or incorporated into product formulations. Proper handling and storage, as advised by a reputable manufacturer, are essential to maintain its chemical integrity.

The molecular formula of DDAB is C26H56BrN, with a molecular weight of approximately 462.634 g/mol. Its exact mass is listed as 461.359619. These precise chemical identifiers are important for accurate calculations in synthesis and formulation. Its LogP value of 5.90860 suggests a significant lipophilicity, which contributes to its effectiveness in bridging hydrophobic and hydrophilic environments. For professionals looking to buy DDAB, understanding these fundamental properties is key to predicting its performance and optimizing its use in applications ranging from catalysis and disinfection to advanced materials.
