2750-44-9 Usage
General Description
BIS(TRIMETHYLSILOXY)DICHLOROSILANE is a chemical compound with the formula (CH3)3SiO)2SiCl2. It is a colorless, volatile liquid that is used as a precursor in the production of silicone polymers. Its chemical structure contains two trimethylsiloxy groups and two chloride atoms bonded to a central silicon atom. It is commonly used as a crosslinking agent in the production of silicone rubber and resins, as well as a coupling agent in the synthesis of organosilane compounds. BIS(TRIMETHYLSILOXY)DICHLOROSILANE is sensitive to moisture and reacts with water to release hydrogen chloride, so it must be handled and stored carefully under dry conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 2750-44-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2750-44:
(6*2)+(5*7)+(4*5)+(3*0)+(2*4)+(1*4)=79
79 % 10 = 9
So 2750-44-9 is a valid CAS Registry Number.

Siloxanes as sources of silanones

Pyrolysis of hexamethyldisiloxane (HMDS) and its copyrolysis with chlorotrimethylsilane and tetrachlorosilane were studied. Based on the data of GLC analysis and on the mass spectrum of the condensate obtained after the pyrolysis of HMDS, it was concluded that HMDS acts as a source of dimethylsilanone. The results of the copyrolysis of HMDS with chlorotrimethylsilane used as a trapping reagent indicate that the dimethylsilanone generated from HMDS can be inserted into the Si-Cl and Si-O bonds. In the copyrolysis of HMDS with tetrachlorosilane serving as a trapping reagent for dimethylsilanone, both dimethylsilanone and dichlorosilanone are generated.
