Descripción general

(3-Aminopropyl) trimethoxysilane (APTMS) is an aminosilane which is used in silanization processes[1] as a silane coupling agent. It functionalizes substrates with alkoxysilane molecules.[2]
(3-Aminopropyl)trimethoxysilane(APTMS) is an amino-silane that is mainly used as a silane coupling agent for the surface modification of a variety of nanomaterials. APTMS based films form a thermally stable layer on different substrates.[3][4]

Aplicación

APTMS can be multilayered on SiOx substrates by a layer by layer self assembly.[1] APTMS has also been used as a silane coupling agent on silver nanoparticles.[2]
APTMS is used for the synthesis of gold nano-bipyramids which can be used as substrates for C-reactive protein (CRP) antibodies that were detected by localized surface plasmon resonance(LSPR).[5] Mesoporous silica matrix can be incorporated with APTMS for the removal of chromium (Cr) from waste water.[6] It can also be used to silanize magnetic iron oxide nanoparticles(MIONPs) for the separation of cross-linked enzyme aggregations (CLEAs) from the reaction medium.[7] It may be coated on TiO2 to improve the power conversion efficiency (PCE) as a critical parameter to assess the overall performance of heterojunction perovskite solar cells (PSCs).[3]

Envase

Optically tunable core-shell composite nanorod structures have been prepared by depositing gold onto silica and titania nanorods which have been surface modified with (3-Aminopropyl)trimethoxysilane[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.
