57-09-0, cetyltrimethylammonium bromide
Cetyltrimethylammonium bromide, commonly known as CTAB, is a quaternary ammonium salt with the chemical formula Câ‚₉Hâ‚„â‚‚BrN and a molecular weight of 364.45 g/mol. It is also referred to by several other names, including Hexadecyltrimethylammonium bromide, Cetrimonium bromide, Palmityl trimethylammonium bromide, and Bromoammonium. The CAS number for this compound is 57-09-0.
CTAB is available in analytical reagent (AR) grade, with a purity of at least 99.0%. It has a moisture content of no more than 0.5%, an acidity level (in Hâº) of ≤1.0 mmol/100g, and passes the ethanol dissolution test. Heavy metal content is limited to ≤0.0005%, and the ignition residue is ≤0.1%. This substance appears as a white microcrystalline powder and is hygroscopic in nature. It remains stable in acidic solutions and dissolves well in water (10 parts), ethanol, but is only slightly soluble in ether and benzene.
The melting point of CTAB ranges from 237 to 243°C. It exhibits moderate toxicity, with an LD₅₀ of 44 mg/kg when administered intravenously to rats. It can cause irritation to the eyes, respiratory system, and skin, so proper handling and safety precautions are recommended.
In terms of applications, CTAB is widely used in biochemical research. It serves as a colorimetric or photometric reagent for the determination of bismuth and tin. It also acts as an inhibitor of intestinal glucose absorption, a phase transfer catalyst in organic reactions such as the reduction of aromatics and epoxidation of olefins, and as a surfactant, fungicide, and disinfectant.
For storage, CTAB should be kept at room temperature (RT) in a cool, dry place away from direct sunlight. Ensure that it is stored in a tightly sealed container to maintain its quality and prevent moisture absorption. Always handle this chemical with care and follow appropriate safety protocols.
