Hexadecyl Trimethyl Ammonium Bromide, with the CAS number 57 - 09 - 0, is a quaternary ammonium salt. It appears as a white to off - white crystalline powder. The molecular formula of this compound is C19H42BrN, and its molecular weight is approximately 364.45 g/mol. It has good solubility in water, ethanol, and chloroform. This product is often supplied by factories in high - purity form and at the best price, ensuring its quality and cost - effectiveness for various applications.
Hexadecyl Trimethyl Ammonium Bromide has a wide range of applications in different industries:
Biotechnology Applications: When using it for nucleic acid extraction, first prepare a solution with an appropriate concentration, usually around 0.1 - 1%. Add the solution to the cell sample and incubate at a suitable temperature (e.g., 65°C) for a certain period to ensure complete cell lysis. Then, perform subsequent purification steps such as centrifugation and precipitation.
Textile Industry: Dissolve the product in water to form a softening bath. The concentration of the solution depends on the type of fabric and the desired softness level. Dip the fabric into the bath and let it soak for a sufficient time, usually 15 - 30 minutes. Then, remove the fabric and rinse it with water to remove any excess softener.
Water Treatment: Calculate the appropriate dosage based on the volume of the water system and the level of contamination. Add the product directly to the water and ensure good mixing. Regularly monitor the water quality parameters to adjust the dosage if necessary.
Case 1: Nucleic Acid Extraction in a Research Laboratory
A research team was working on a project to study the genetic material of a specific virus. They used Hexadecyl Trimethyl Ammonium Bromide for nucleic acid extraction. By following the standard protocol of preparing a 0.5% solution and incubating the virus - infected cell samples at 65°C for 20 minutes, they were able to obtain high - quality nucleic acids. These nucleic acids were then used for subsequent PCR amplification and sequencing, which helped them in understanding the genetic characteristics of the virus and developing potential diagnostic methods.
Case 2: Fabric Softening in a Textile Factory
A textile factory was facing problems with the static electricity of their synthetic fabrics, which affected the production efficiency and the quality of the final products. They decided to use Hexadecyl Trimethyl Ammonium Bromide as a fabric softener. They prepared a 0.2% solution in a large - scale softening bath. After treating the fabrics, they found that the static electricity was significantly reduced, and the fabrics became softer and more pleasant to touch. This improvement led to an increase in customer satisfaction and a boost in sales.
Case 3: Water Treatment in a Swimming Pool
A public swimming pool was experiencing algae growth and high levels of bacteria, which affected the water quality and the safety of the swimmers.
