性状描述：白色微晶形粉末。熔点>230℃（分解）。溶于水，微溶于醇，不溶于醚。水溶液呈碱性，产生大量气泡，具刺鼻臭味。

生产方法：由十六醇经溴素溴化后与三甲胺反应生成季铵盐。

用途：用于有机合成，也可作为阳离子表面活性剂，用作杀菌剂，配制含漱剂、消毒剂，肠内葡萄糖吸收抑制剂。该品也是常用的胶束增溶分光光度法试剂。

楼上的瞎侃，怎么会很大毒呢？！

同意三楼，CTAB是很常用的表面活性剂，而且效果很不错

2楼在不懂装懂吧？
我经常用

各位做一下mtt就知道了，

Detoxification of gold nanorods by treatment with polystyrenesulfonate
Authors: Alexei P Leonov, Jiwen Zheng, Jeffrey D Clogston, Stephan T Stern, Anil K Patri, Alexander Wei

Journal: ACS Nano
We address an outstanding issue associated with the biocompatibility of gold nanorods (GNRs), a promising agent for biomedical imaging and theragnostics. GNRs are typically prepared in the presence of cetyltrimethylammonium bromide (CTAB), a cationic surfactant whose rigorous removal is necessary due to its cytotoxicity and membrane-compromising properties. CTAB-stabilized GNRs can be partially purified by treatment with polystyrenesulfonate (PSS), an anionic polyelectrolyte often used as a surrogate peptizing agent, followed by chloroform extraction and ultrafiltration with minimal loss of dispersion stability. However, in vitro cytotoxicity assays of PSS-coated GNRs revealed IC(50) values in the low to submicromolar range, with subsequent studies indicating the source of toxicity to be associated with a persistent PSS-CTAB complex. Further exchange of CTAB-laden PSS with fresh polyelectrolyte greatly improves biocompatibility, to the extent that 85 microg/mL of "CTAB-free" GNRs (the highest level evaluated) has comparable toxicity to a standard phosphate buffer solution. Ironically, PSS is not effective by itself at stabilizing GNRs in CTAB-depleted suspensions: while useful as a detergent for GNR detoxification, it should be replaced by more robust coatings for long-term stability under physiological conditions
