Explore our highly integrated industrial-grade and cosmetic-grade ingredients customized for dynamic formulation needs.
Cetyl Trimethyl Ammonium Bromide, structurally recognized as hexadecyltrimethylammonium bromide (CAS 57-09-0), is an exceptional quaternary ammonium cationic surfactant. Owing to its long hydrophobic alkyl chain and hydrophilic quaternary head group, CTAB excels as a structural directing agent, phase transfer catalyst, and protein-nucleic acid precipitator in biochemical industries.
As a leading supplier and exporter, Suzhou Yuantairun Chemical ensures that our CTAB meets stringent industrial, pharmaceutical, and molecular biology grades. The molecule forms micelles at low concentrations, which allows it to isolate and complex nucleic acids, synthesize high-aspect-ratio gold nanorods, and impart premium antistatic and conditioning characteristics to high-performance personal care formulas.

Common questions from B2B chemical buyers, research engineers, and formulation technicians regarding CTAB application.
The Critical Micelle Concentration of CTAB in pure water is approximately 0.9 to 1.0 mM at 25°C. This parameter changes depending on the ionic strength and salt content of the surrounding solution.
CTAB is hygroscopic and should be stored in tightly sealed containers in a cool, dry, and well-ventilated warehouse. Keep containers away from strong oxidizing agents and moisture to prevent clumping.
In genomic extraction, plant tissue is rich in polysaccharides and polyphenols that co-precipitate with DNA. CTAB forms complexes with nucleic acids under high-salt conditions, allowing the separation of polysaccharides during wash phases.
Yes, as a cationic quaternary ammonium compound, CTAB exhibits broad-spectrum antimicrobial activity against gram-positive bacteria and fungi by disrupting cell membrane structures.
CTAB contains a bromide counterion, while CTAC (Cetrimonium Chloride) contains a chloride ion. While similar in action, CTAB is more hydrophobic and crystallizes easily, making it preferred for purification templates.
We provide industrial-standard packaging, including 25kg fiber drums with double PE inner liners, as well as customized packaging sizes for bulk pharmaceutical and industrial orders.
In the European Union, CTAB is subject to concentration limits under Annex V. When used as a preservative, its concentration in rinse-off products must not exceed 0.1% active substance.
Yes. Depending on your application—whether biology-grade extraction or industrial-scale phase catalysis—we can adjust synthesis and recrystallization stages to meet your specific purity targets.
