678-26-2 Usage

Uses

Different sources of media describe the Uses of 678-26-2 differently. You can refer to the following data:
1. Diagnostic aid. [Note—The trademark EchoGen Emulsion has been selected for the mixture of Perflenapent and Perflisopent in a ratio of 85:15, respectively.
2. Perfluoro-n-pentane is used in method for producing bubble formulation for theranostics.

Check Digit Verification of cas no

The CAS Registry Mumber 678-26-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,7 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 678-26:
(5*6)+(4*7)+(3*8)+(2*2)+(1*6)=92
92 % 10 = 2
So 678-26-2 is a valid CAS Registry Number.

Combined preparations comprising an injectable gas dispersion and a coadministrable diffusible component which is capable of inward diffusion into the dispersed gas so as to promote temporary growth of the gas in vivo, the preparations being for use as contrast agents in ultrasound cardiac studies of patients who have undergone physical exercise-induced stress in order to promote vasodilatation.

Electrochemical fluorination of hexahydroazepine, methylpiperidines and methyl 1-hexahydroazepine-acetate: The preparation of F-(1-hexahydroazepine-acetyl fluoride) and its derivatives

Abe, Takashi,Pandey, Sushil K.,Baba, Hajime

, p. 149 - 157 (2007/10/03)

The electrochemical fluorination of hexahydroazepine (1), methylpiperidines (2) [2-methylpiperidine (2a), 3-methylpiperidine (2b), 4-methylpiperidine (2c)] and methyl 1-hexahydroazepine-acetate (3) was examined. An extensive cleavage of the C-N bond occurred in the fluorination of secondary cyclic amines (1, 2a-c) resulting in only a small yield of the corresponding F-(N-fluoro cyclic amines). F-(1-hexahydroazepine-acetyl fluoride) (4) was obtained in a fair yield from the fluorination of 3 along with F-[(methylpiperidino)-acetylfluoride] which was formed as a result of the isomerization of 3 during fluorination. In addition, several derivatives of 4 were synthesized. F-(1-iodomethyl-hexahydroazepine) (4a) was prepared by the reaction of 4 with anhydrous LiI. The compound 4 was converted into its potassium salt (4c) via methyl F-(1-hexahydroazepine-acetate) (4b), which upon pyrolysis in the presence or absence of ethylene glycol resulted in the formation of 1-difluoromethyl-dodecafluoro(hexahydroazepine) (4d) and F-(3,4,5,6-tetrahydroazepine) (4e), respectively. F-(1-hexahydroazepine-acetoamide) (4f), F-(1-hexahydroazepine-acetonitrile) (4g) and corresponding p-methoxyanilide (4h) were also derived from 4.
