Descripción general

1,2-Bis(triethoxysilyl)ethane (BTESE) is a silsesquioxane precursor which is mainly used in the preparation of mesoporous organic materials. It can tune silica networks which makes them useful in applications related to molecular separation.[1][2]
1,2-bis(triethoxysilyl)ethane is a non-functional silane and a double trialkoxysilyl precursor.

Aplicación

1,2-bis(triethoxysilyl)ethane may be used to prepare mesoporous organosilica materials. Amine functionalization of mesoporous silica can be undertaken by this silane. It may form inorganic hybrid membranes with poly(vinyl alcohol). Effect of this crosslinking silane on the bonding of bis-GMA (bis-phenol-A-diglycidyldimethacrylate) resin to silicatized titanium was investigated.
BTESE can be used as an anti-corrosive coating on aluminium magnesium alloy (Al93Mg7) for potential application in nuclear and food processing industries.[3] BTESE membranes are chlorine resistant and can be thermally stable at 100°C. They which can be used in gas permeation (GS) and reverse osmosis (RO) applications.[2] It may also form a mesoporous hybrid monolith with tetramethoxysilane by a sol-gel condensation method with enhanced chemical stability for peptide separation.[4]

Questions

1–2 of 2 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
