Product Overview

(1-Hexadecyl) trimethylammonium bromide, commonly known as CTAB (Cetyltrimethylammonium bromide), is a high-purity quaternary ammonium salt with a 98% assay. This compound is widely recognized for its role as a cationic surfactant, making it valuable in various laboratory applications. The solid form, typically available as a fine powder or crystalline structure, ensures stability and ease of handling. Its molecular structure features a long hydrophobic hexadecyl chain and a positively charged trimethylammonium group, which contributes to its surfactant properties. This dual nature allows it to interact effectively with both polar and nonpolar substances, making it useful in emulsification, micelle formation, and phase transfer catalysis. The 98% purity grade ensures minimal impurities, which is critical for reproducible results in sensitive applications. Its solubility in water and polar solvents further enhances its versatility in lab protocols. Whether used in small-scale experiments or bulk preparations, this compound maintains consistent performance, making it a reliable choice for researchers and students alike.

FAQs

1. What is the solubility of (1-Hexadecyl) trimethylammonium bromide in water?

It is soluble in water, forming a clear to slightly turbid solution depending on concentration. It also dissolves well in polar organic solvents like methanol and ethanol.

2. Can this compound be used as a phase transfer catalyst?

Yes, due to its cationic nature and long hydrophobic chain, it effectively facilitates phase transfer reactions by transporting reactants between aqueous and organic phases.

3. How should this chemical be stored for long-term stability?

Store in a tightly sealed container at room temperature, away from moisture and direct sunlight. Keep it in a dry, well-ventilated area to prevent degradation.

4. Is this product compatible with anionic surfactants?

No, it may form insoluble complexes with anionic surfactants due to charge interactions, leading to precipitation or reduced effectiveness in mixed systems.

5. What alternatives exist for similar cationic surfactant applications?

Alternatives include cetylpyridinium chloride, benzalkonium chloride, or other quaternary ammonium compounds, though their properties may vary slightly in terms of solubility and micelle formation.
