42557-10-8 Usage
Physical properties
colorless free-flowing liquid; average molecular weight is supplier dependent; d 0.98 gmL?1Uses
PDMS Thimbles? can be used in Differential Flux of Reagents and Catalysts ThroughPDMS Thimbles. In summary, a wide variety of organic molecules with various functional groups flux throughPDMSthimbles, but care should be taken to consider the solvent, thickness of the walls, temperature, and the presence of any ionic functional group.Preparation
reaction between dimethylchlorosiloxane and water yields PDMS. The anionic polymerization of hexamethylcyclotrisiloxane yields PDMS. PDMS thimbles are fabricated by curing Sylgard 184 in an oven.Check Digit Verification of cas no
The CAS Registry Mumber 42557-10-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,5 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.Calculate Digit Verification of CAS Registry Number 42557-10:
(7*4)+(6*2)+(5*5)+(4*5)+(3*7)+(2*1)+(1*0)=108
108 % 10 = 8
So 42557-10-8 is a valid CAS Registry Number.
