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.

General description
Its amphiphilic structure, featuring a 18-carbon octadecyl chain and a highly polar trichlorosilyl head group, ensures rapid covalent bonding to surfaces like glass, silicon, and ceramics. This molecular architecture allows for the creation of thin insulating gates and non-polar interphases that effectively shield sensitive electronic components from water vapor and environmental degradation.
Widely recognized as a benchmark material in molecular electronics, OTS provides a terminal methyl handle for tuning the wetting, friction, and adhesion properties of substrates at an ultra-fine scale.
Refined to a ≥90% high-purity specification, this grade is optimized for consistency in research and industrial processes requiring reliable surface passivation and improved compatibility between organic and inorganic phases.
Application
High-Mobility Nanoelectronics: Primarily used to form Self-Assembled Monolayers (SAMs) on gate dielectrics in Organic Field-Effect Transistors (OFETs). It passivates the surface to reduce charge-trapping, significantly enhancing charge-carrier mobility in materials like pentacene and P3HT.
Graphene Device Optimization: Employed as a substrate modifier for graphene transistors to achieve low intrinsic doping and high carrier mobility on conventional substrates.
Precision Biosensing: Serves as a chemical sensor interface for immobilizing physiologically active cell organelles and proteins. Its long hydrophobic chain enables fine-scale lithography and chemical patterning essential for point-of-care diagnostic arrays.
Advanced Photovoltaics: Applied in dye-sensitized solar cells to improve electrochemical performance by controlling interface kinetics and reducing recombination.
Nanofiber Functionalization: Used to silanize electrospun nanofibers for the development of moisture-resistant, hydrophobic coatings in smart materials and environmental sensors.

Bonjour, Serait-il possible de savoir si ce produit est proposé préalablement scellé avec un septum, compte tenu de sa grande sensibilité à l'air Merci,
1 answer-
This product is packaged in glass bottles with screw caps that include an HDPE/PTFE liner rather than a septum. Currently, there is not product available with a septum closure.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
