Descripción general

Trimethoxymethylsilane (MTM) is an organosilicon compound widely used as a precursor for the preparation of silica-based materials, which finds the applications in various fields. Particularly in molecular assembly, linking nano building blocks, and selective synthesis oligosiloxane compounds. It can also be utilized as a crosslinker in the synthesis of polysiloxane polymers.[1][2]

Aplicación

Trimethoxymethylsilane can be used:
  • As a silica source for synthesizing polyethyleneimine-silica (PEI-silica) organic-inorganic hybrid particles.[3]
  • To transform hydrophilic ceramic surfaces to hydrophobic by modifying the -OH groups.[4]
  • To modify silica aerogels by inducing hydrophobicity and enhancing mechanical properties without affecting transparency.[5]

The commercially practiced conversion of trimethoxymethylsilane (MTM) to [OSi(OMe)Me)]n polymers and resins is assumed to proceed via the silanol (MeO)2MeSiOH. Access to this crucial silanol is gained via the synthesis of (MeO)2MeSiONa, the first methoxysilanoate to be crystallographically characterized. Mild

Questions

1–3 of 3 Questions  
  1. 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.

  2. 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
