Anwendung

3-(Triethoxysilyl)propyl isocyanate can be used:
  • As a bifunctional reagent (isocyanate and ethoxysilyl groups) for the immobilization of cellulose derivatives onto silica matrix to generate bonded type of chiral stationary phases (CSPs).[1]
  • To convert 5-amino-1,10-phenanthroline into 5-(N,N-bis-3-(triethoxysilyl)propyl)-ureyl-1,10-phenanthroline, a hydrolysable sol–gel precursor.[2]
  • To synthesize ruthenium bipyridyl tethered porous organosilica(Ru-POS) for organo-photocatalysis.[3]
  • To synthesize nanoparticle-supported oxime palladacycle catalyst for Suzuki-Miyaura cross-coupling reaction.[4]

3-(triethoxysilyl)propyl isocyanate (TEPI) was used as a spacer reagent to prepare cellulose based chiral stationary phases (CSPs). [5] TEPI may be used to modify 2-hydroxynicotinic acid to prepare luminescent hybrid materials.[6]2 Luminescent inorganic-organic hybrid materials were prepared by grafting the isocynate with the ortho aminobenzoic acid derivative. [7] TEPI may also be used to prepare 5-(N,N-bis-3-(triethoxysilyl)propyl)ureyl-1,10- phenanthroline (phen-Si).[8]

Questions

1–2 of 2 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
