    24424-99-5是二碳酸二叔丁酯(BOC酸酐)的CAS編號 基本參數(shù)信息: 產(chǎn)品名稱 二碳酸二叔丁酯(BOC酸酐) CAS編號 24424-99-5 分子式 C10H18O5 分子量 218.25 外觀 透明晶體或液體 熔點 22.4-23.8℃ 規(guī)格 99%以上 24424-99-5用途: 1、是有機合成中用來引入叔丁氧羰基保護基因,特別運用于氨基酸的氨基保護。廣泛應(yīng)用于醫(yī)藥、蛋白質(zhì)及多肽合成、生物化學(xué)食品、化妝品等多種產(chǎn)品的合成中。 2、 24424-99-5安全性:要合成一種與天然多肽相同的化合物,必須把各種旋光性的氨基酸按一定順序連接成一定長度的肽鏈,在需要使一種氨基酸的羧基和另一種氨基酸的氨基相結(jié)合時,要防止同一種氨基酸分子之間相互結(jié)合,因此,在合成時,必須把某些氨基或羧基保護起來,以便反應(yīng)能按所要求的方式進行。 3、 24424-99-5是一種性能良好的氨基酸保護劑,較之傳統(tǒng)的氨基酸保護劑如氯甲酸芐酯,氯甲酸-P芴甲酸等相比,它具有如下優(yōu)點: a、價格便宜 b、無強烈刺激性味道,對人體無毒害作用,但對直接接觸皮膚好可引起皮膚過敏,用水沖洗。 c、采用本產(chǎn)品合成多肽時,該保護基因的脫除條件溫和,且反應(yīng)好產(chǎn)物的分離提純較之使用其 他類型的氨基酸保護劑容易。 d、具可燃性,但不屬于易燃易爆品。 樓主有需求的話 可以聯(lián)系金象化工 http://www.jinchemical.com/productShow-95.html

During the preparation of the nano-products, these nano-units, such as nanoparticles, nanoclusters, nanowires and nanorods, can also self-assemble into the novel structural aggregates by several routes, including electron irradiation deposition [19], chemical vapor deposition [20], laser vaporization-condensation [21], charge transferring [22], an organic reagent-assisted method [23], solution-liquid-solid method [24] and catalytic vapor-liquid-solid growth [25]. With these routes, various nanoscale or microscale aggregates can demonstrate novel architectures, including tree-like, web-like, spherical, nanowire-like, network and fishbone-like aggregates. As a well-known method for producing the nanocapsules, however, arc-discharge has been rarely used to synthesize the aggregates self-assembled by the nanocapsules prepared simultaneously in arc-discharge. Nevertheless, it is possible that the arc-discharge can be developed into a new way to synthesize the aggregates. In the present work, we utilized arc-discharge technique with modified strategies, involving changing the hydrogen pressure, introducing gadolinium - aluminum alloy ingot as the anode and adjusting the elements percent of the anode according to their evaporation pressure, to synthesize a new type of nanocapsules, with intermetallic compound GdAl2 as core and amorphous Al2O3 as shell, which enlarge the family of the magnetic nanocapsules. At the same time, the regularly aligned three-dimensional macro-aggregates self-assembled by the nanocapsules without any template and catalyst were simultaneously synthesized in arc-discharge process. 展開
