3069-42-9 Usage

Chemical Properties

Colorless transparent liquid

Uses

Different sources of media describe the Uses of 3069-42-9 differently. You can refer to the following data:
1. For preparing hydrophobic coatings and self-assembled monolayers.
2. OTS is used for the development of self assembled monolayers(SAMs). OTS is also used to modify the silica dielectric surface in organic field effect transistors.

General Description

Trimethoxy(octadecyl)silane (OTS) is an important alkylsilane that can form strong covalent bonds with silicon oxide and serves as a potential lubricant for micro electro mechanical systems (MEMS). OTS is largely used for surface chemical modification, modifying silica resulted in an increased charge carrier mobility for a variety of vacuum deposited and solution cast organic semiconductors.

Check Digit Verification of cas no

The CAS Registry Mumber 3069-42-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,6 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3069-42:
(6*3)+(5*0)+(4*6)+(3*9)+(2*4)+(1*2)=79
79 % 10 = 9
So 3069-42-9 is a valid CAS Registry Number.

An Easily Accessed Nickel Nanoparticle Catalyst for Alkene Hydrosilylation with Tertiary Silanes

Buslov, Ivan,Song, Fang,Hu, Xile

supporting information, p. 12295 - 12299 (2016/10/13)

The first efficient and non-precious nanoparticle catalyst for alkene hydrosilylation with commercially relevant tertiary silanes has been developed. The nickel nanoparticle catalyst was prepared in situ from a simple nickel alkoxide precatalyst Ni(OtBu)2?x KCl. The catalyst exhibits high activity for anti-Markovnikov hydrosilylation of unactivated terminal alkenes and isomerizing hydrosilylation of internal alkenes. The catalyst can be applied to synthesize a single terminal alkyl silane from a mixture of internal and terminal alkene isomers, and to remotely functionalize an internal alkene derived from a fatty acid.

Method for Attachment of Silicon-Containing Compounds to a Surface and for Synthesis of Hypervalent Silicon-Compounds

-

, (2012/06/01)

A method for inducing a hypervalent state within silicon-containing compounds by which they can be chemically attached to a surface or substrate and/or organized onto a surface of a substrate. The compounds when attached to or organized on the surface may have different physical and/or chemical properties compared to the starting materials.
