l巯基丙基QuadraSi

中文描述 巯基丙基QuadraSil（QuadraSil）** 是一种高性能巯基丙基功能化硅胶基质（CAS: 1225327-73-0）。外观为白色至奶油色的多孔微球或粉末**，粒径通常为20-100微米。其表面高密度键合活性巯基（-SH）*官能团，负载量达1.0-1.8mmol/g。作为专用金属捕捉剂，它能高效、选择性地络合与去除水溶液或有机体系中的钯（Pd）、铑（Rh）、铜（Cu）、钌（Ru）、铂（Pt）、铅（Pb）、银（Ag）、汞（Hg） 等多种重金属离子及纳米颗粒。广泛用于**医药中间体、精细化工合成**（如Suzuki-Miyaura偶联反应）后的产品纯化、催化剂回收与贵金属脱除，以及环境水样的重金属富集处理，具有吸附容量高、速率快、易分离、化学稳定性好**的优势。 #English Description **Mercaptopropyl QuadraSil (QuadraSil® MP)** is a high-performance **silica-based mercaptopropyl functionalized resin** (CAS: 1225327-73-0). It appears as **white to cream-colored porous microspheres or powder** with a typical particle size of 20-100 microns. The surface is densely grafted with reactive **thiol (-SH)** groups at a **loading capacity of 1.0-1.5 mmol/g**. As a specialized **metal scavenger**, it efficiently and selectively complexes and removes heavy metal ions and nanoparticles, including **Pd, Rh, Cu, Ru, Pt, Pb, Ag, and Hg**, from aqueous or organic solutions. It is widely used for **product purification, catalyst recovery, and precious metal removal** in the synthesis of pharmaceutical intermediates and fine chemicals (e.g., Suzuki-Miyaura coupling reactions), as well as for heavy metal enrichment in environmental water samples. It offers advantages of **high adsorption capacity, fast kinetics, easy separation, and excellent chemical stability**.
