General Description
(ISOCYANATOMETHYL)METHYLDIMETHOXYSILANE is a chemical compound with the molecular formula C6H13NO3Si. It is a silane compound with a branched alkyl group and two methoxy groups attached to a silicon atom. The isocyanatomethyl group is a functional group that contains both an isocyanate and a methyl group. (ISOCYANATOMETHYL)METHYLDIMETHOXYSILANE is commonly used as a precursor in the synthesis of polyurethane polymers and as a crosslinking agent in adhesives and sealants. It can also be used as a coupling agent in organic-inorganic hybrid materials, where its silane functionality allows it to bond to surfaces and improve adhesion. Additionally, it is a useful intermediate in the production of various organosilicon compounds for industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 406679-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,6,6,7 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 406679-89:
(8*4)+(7*0)+(6*6)+(5*6)+(4*7)+(3*9)+(2*8)+(1*9)=178
178 % 10 = 8
So 406679-89-8 is a valid CAS Registry Number.

PRODUCTION OF ISOCYANATE FUNCTIONAL ORGANOSILANES
-
Paragraph 0080-0085; 0108-0109, (2017/11/30)
Isocyanate-functional silanes are prepared in high yield by pyrolysis of an O-carbamate prepared by reaction of a dialkylcarbonate with an aminoalkyl-functional silane in the presence of a basic catalyst, where the catalyst is neutralized by an acid which has a pKa of all protolysis stages of not more than 4. The neutralized or partially neutralized catalyst need not be removed prior to pyrolysis. The isocyanato-functional silanes exhibit higher storage stability as compared to those prepared from O-carbamates where catalyst neutralization is effected by weak acids.
