If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

一般描述
应用
- 试剂，通过形成三甲基硅基醚和三甲基硅基胺保护醇基和胺基。[2][3]
- 催化剂，用于制备抗菌剂1,3-二苯基-2-丙烯酮衍生物（查耳酮）。[3]
- 捕获剂，捕获偶姻缩合反应过程中产生的阴离子。[4]
- 更好的催化剂，替代有毒氯化汞，在烯丙型醇和α丙二烯型醇环丙烷化反应中活化钐（Sm）。[5]
- 催化剂，催化甘油三酸酯与醇进行酯交换反应形成脂肪酸烷基酯。[6]
- 试剂，和溴化锂一起将醇转化为相应溴化物。[7]
- 试剂，用于Fisher糖基化。[8]
- 酸催化剂来源，用于苯甲醛和Et3SiH进行还原苄化反应。[9]
- 试剂，与硫化钠反应合成三甲基硅硫醇钠(Me3SiSNa)；这一合成方案无味，可替代有恶臭气味的双(三甲基硫化硅)与甲氧基钠合成Me3SiSNa的方法。[10]

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
