Product Overview
Dodecyltrimethylammonium bromide (DTAB) is a high-purity cationic surfactant widely used in laboratory settings for its excellent micelle-forming properties and colloidal stability. With a 99% assay, this reagent ensures reliable results in phase behavior studies, interfacial tension measurements, and surfactant-based research. Its quaternary ammonium structure provides strong surface activity, making it ideal for experiments requiring controlled aggregation and self-assembly. The powder form allows for precise weighing and easy dissolution in aqueous solutions, ensuring reproducibility in experimental protocols. DTAB is particularly valued in physicochemical studies due to its well-defined critical micelle concentration (CMC) and predictable behavior in mixed surfactant systems. Whether used in fundamental research or applied studies, this grade of DTAB delivers consistent performance, minimizing variability in experimental outcomes. The product is packaged in airtight containers to maintain purity and prevent moisture absorption, ensuring long-term stability under proper storage conditions.
FAQs
1. What is the solubility of DTAB in water?
DTAB is highly soluble in water, forming clear solutions at concentrations well above its critical micelle concentration (CMC). The solubility increases with temperature, making it suitable for a wide range of experimental conditions.
2. Can DTAB be used with anionic surfactants?
DTAB can interact with anionic surfactants, often leading to precipitation or complex formation due to charge neutralization. Compatibility should be tested case-by-case depending on the specific application and concentration ratios.
3. What is the typical shelf life of this product?
When stored in a cool, dry place away from direct sunlight and moisture, DTAB maintains its purity and effectiveness for at least 24 months from the date of manufacture.
4. How should DTAB be stored to prevent degradation?
Store DTAB in its original, tightly sealed container at room temperature (15–25°C). Avoid exposure to humidity or extreme temperatures, as moisture can cause clumping and reduce the product’s efficacy.
5. Is this DTAB suitable for biological applications?
While DTAB is primarily used in physicochemical studies, its cationic nature may disrupt cell membranes, making it less ideal for direct biological applications without further purification or modification.
