一般描述

六甲基二硅烷(HMDS)是稳定有效的氢不稳定类物质的三甲基硅烷化反应试剂,如醇、胺和脂肪酸。常用于在化学合成时保护敏感的官能基团。因其低成本、高蒸气压和安全性,广泛用作化学气相沉积(CVD)反应前体。

应用

六甲基二硅烷(HMDS)可用于:
  • 作为硅烷化剂,用于近中性条件下醇类的三甲基硅烷化反应。
  • 在α-氨基酸N-羧基酸酐的开环聚合反应中控制多肽分子量。
  • 通过等离子体增强化学气相沉积(CVD)制备碳氮化硅薄膜。
  • 用于扫描电镜的标本制备,以及羟基化合物制备三甲基硅醚。

特点和优势

  • 强化学稳定性和低分子量
  • 无毒性的实惠试剂
  • 硅烷化反应的唯一副产物只有氨
  • HDMS硅烷化反应近中性,无需采取任何特别措施

Spintronics offer breakthroughs over conventional memory/logic devices with lower power, leakage, saturation, and complexity.

Hybrid organic-inorganic sol-gel materials containing silica were first called “ORMOSILs” in 1984.

The properties of many devices are limited by the intrinsic properties of the materials that compose them.

Questions

1–3 of 3 Questions  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. What is the storage temperature of this reagent?

    1 answer
    1. This product may be stored at room temperature. For products with no specified storage temperature given on the label or product page, ambient storage may be assumed. Products that require controlled temperature storage, such as refrigeration or freezer conditions, storage temperatures are published on the product label, Certificate of Analysis, the Safety Data Sheet (SDS).
