125070-38-4 Usage
General Description
4,4,5,5,6,6,7,7,7-Nonafluoroheptane-1,2-diol is a fluorinated compound with a molecular formula C7F16O2. It is a colorless liquid and is often used as a building block in the synthesis of other fluorochemicals such as surfactants and polymers. Due to its unique chemical structure, it exhibits excellent chemical and thermal stability, making it useful for a wide range of industrial applications. Additionally, it also has surfactant properties and can be used as a wetting agent or emulsifier in various formulations. However, its potential environmental and health effects are still under investigation, and caution should be exercised in its handling and use.
Check Digit Verification of cas no
The CAS Registry Mumber 125070-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,0,7 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 125070-38:
(8*1)+(7*2)+(6*5)+(5*0)+(4*7)+(3*0)+(2*3)+(1*8)=94
94 % 10 = 4
So 125070-38-4 is a valid CAS Registry Number.

Chemistry of [(perfluoroalkyl)methyl] oxiranes. Regioselectivity of ring opening with O-nucleophiles and the preparation of amphiphilic monomers
Cirkva, Vladimir,Ameduri, Bruno,Boutevin, Bernard,Paleta, Oldrich

The reactions of oxiranes RFCH2CH(-O-)CH2 (RF≡C4F9, C6F13, C8F17; 4a-4c) with a series of alkanols in the presence of a Lewis acid took place at the terminal carbon atom with complete regioselectivity. 2-Hydroxyethyl methacrylate and acrylate reacted similarly. The reaction with alkane diols was controlled to proceed with one or two molecules of the oxiranes chemoselectively. Non-regioselective, base-catalysed ring opening by methacrylic acid (83% terminal attack) was discussed on the basis of the hard and soft acids and bases (HSAB) concept. A convenient transformation of the oxiranes to the corresponding diols 13a-13c via dioxolane intermediates, and their conversion to bis-methacrylates, was accomplished with overall yields of 75%-79%. Thiourea converted the oxiranes into the corresponding thiiranes (15a-15c). The reactions afforded products generally in yields of 82%-98%.
