356-47-8 Usage
General Description
2,2,3,3,4,4,5,5,6-nonafluorotetrahydro-6-(trifluoromethyl)-2H-pyran is a chemical compound with the molecular formula C8F17O that is commonly used as a solvent and in the production of fluoropolymers. It is a colorless, volatile liquid with a slightly sweet odor and is highly stable and non-reactive. 2,2,3,3,4,4,5,5,6-nonafluorotetrahydro-6-(trifluoromethyl)-2H-pyran is a perfluorinated ether, which means that all of the hydrogen atoms in the molecule have been replaced by fluorine atoms. It is known for its low surface tension, high stability, and non-flammability, making it a useful substance in various industrial applications such as lubricants, heat transfer fluids, and electronic components. However, it is also known to persist in the environment and is a potential environmental hazard due to its long atmospheric lifetime.
Check Digit Verification of cas no
The CAS Registry Mumber 356-47-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 356-47:
(5*3)+(4*5)+(3*6)+(2*4)+(1*7)=68
68 % 10 = 8
So 356-47-8 is a valid CAS Registry Number.

Electrochemical fluorination (ECF) of the ester derivatives of oxolane-2-yl-carboxylic acid (1), oxolane-2-yl-methanol (2) and oxane-2-yl-methanol (3) were investigated. Perfluoro(oxolane-2-yl- carbonylfluoride) (4) was obtained from derivatives of 1 and 2, and perfluoro(oxane-2-yl-carbonylfluoride) (5) was obtained from derivatives of 3 as the desired compounds, respectively. From the ECF of acetates of 2 and 3, perfluorospiroethers having a dioxolane ring were also obtained as the cyclization product in low yield together with the desired perfluoroacid fluoride (4 and 5). The structure of these perfluorospiroethers was confirmed by analyzing the chlorinated products, which were obtained by the reaction with AlCl3.
