Product Overview

Hexadecyltrimethylammonium hydroxide (CTA-OH) in 25% methanol solution is a high-purity cationic surfactant designed for laboratory applications requiring precise control over micelle formation and surface activity. This methanol-based solution offers enhanced solubility compared to solid CTAB, making it ideal for applications where uniform dispersion is critical. The 25% concentration provides an optimal balance between reactivity and handling convenience, eliminating the need for dilution in most standard protocols. As a quaternary ammonium compound, it maintains stability across a wide pH range while exhibiting strong antimicrobial properties. The methanol solvent system ensures compatibility with both aqueous and organic reaction media, facilitating its use in biphasic systems. This laboratory-grade solution undergoes rigorous purification to minimize trace impurities that could interfere with sensitive analytical techniques or nanoparticle synthesis. The product is packaged in amber glass bottles to prevent photodegradation and maintain long-term stability under proper storage conditions.

FAQs

1. What is the shelf life of this 25% CTAB hydroxide methanol solution?

When stored unopened at room temperature in its original container, the solution maintains its specified properties for 24 months from the date of manufacture. Exposure to light or repeated opening may reduce stability.

2. Can this solution be used directly in aqueous systems without further dilution?

The 25% concentration is designed for direct use in most standard protocols, though some applications may require dilution depending on the desired critical micelle concentration and specific reaction conditions.

3. What precautions should be taken when handling this methanol-based solution?

Standard laboratory safety measures for methanol handling apply, including use in a fume hood, nitrile gloves, and safety goggles. The solution is flammable and should be kept away from ignition sources.

4. How does this compare to solid CTAB hydroxide in terms of application?

The methanol solution offers immediate solubility and eliminates the need for dissolution steps, providing more consistent results in time-sensitive applications compared to solid CTAB hydroxide.
