Cycloheptasiloxane, also known as D7, is a cyclic volatile methylsiloxane compound with the chemical formula (CH3)2SiO)7. It is a colorless, odorless, and non-toxic liquid that is widely used in various industrial applications, such as personal care products, household products, and industrial processes. Cycloheptasiloxane serves as a solvent, carrier fluid, and spreading agent, providing benefits like improved wetting, faster drying, and enhanced product performance. However, due to concerns over its potential environmental and health impacts, such as bioaccumulation and endocrine disruption, its use has been restricted or banned in some regions, prompting the development of alternative, safer siloxane compounds.

295-47-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 295-47-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 295-47:
(5*2)+(4*9)+(3*5)+(2*4)+(1*7)=76
76 % 10 = 6
So 295-47-6 is a valid CAS Registry Number.

Linear polysiloxanes from dichlorosilane

Seyferth, Dietmar,Prud'homme, Christian C.

, p. 4412 - 4417 (2008/10/08)

Polysiloxanes of type RR′R″SiO(SiH2O)nSiRR′R″ (R, R′, R″ = Me, Me, Me; Me, H, H; Et, Et, Et; Me, Me, H) have been prepared by three different methods: (1) reactions of ClSiH2O(SiH2O)nSiH2Cl with CH3MgBr, Me3SiOH, and Et3SiOH; (2) H2SO4-catalyzed equilibration of cyclic [H2SiO]n oligomers with Me3SiOSiMe3; (3) cohydrolysis of H2SiCl2 with Me3SiCl and Me2HSiCl using NaH2PO4/Na2HPO4-buffered media. Lower species, Me2RSiO(SiH2O)nSiMe2R (n = 1-3), were isolated and characterized (R = Me, H).
