Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

应用

二氯二甲基硅烷(DDMS)可以用作Pd/SiO2催化剂甲硅烷基化的甲硅烷基化剂，以增强对芳香族酮选择性氢化的催化活性。[1][2]
它还被用作由未保护氨基酸合成亲水性和疏水性二氧化硅纳米粒子和酰胺的试剂。[3][4]

其他说明

用于二醇、二胺等的甲硅烷基化剂；其保护对水解非常敏感 [5][6][7][8]
