423-55-2 Usage

Chemical Properties

clear colorless liquid

Uses

Different sources of media describe the Uses of 423-55-2 differently. You can refer to the following data:
1. 1-BroMoheptadecafluorooctane can be used as oxygen carrier in emulsions used as blood substitutes.
2. 1-Bromoperfluorooctane 1-Bromoheptadecafluorooctane (perfluorooctyl bromide) can be used as contrast agent in the vascular system for fluorine-19 magnetic resonance imaging or as synthetic oxygen carrier. It is used as an O2 carrier in some emulsions.

Application

It is physiologically inert and is useful as an X-ray contrast agent, especially for lung examinations. With its low surface tension it penetrates small spaces and evenly wets healthy lung tissue.

Brand name

Imagent (Alliance).

General Description

1-Bromoheptadecafluorooctane (perfluorooctyl bromide) is a perfluorocarbon. Poly(ethylene glycol)ylated polyester nanocapsules of perfluorooctyl bromide were surface-decorated with a RGD (arginine-glycine-aspartic acid) peptide, were used for tumor imaging. Nanocapsules of perfluorooctyl bromide have been developed as dual contrast agent for ultrasonography and Magnetic Resonance Imaging (MRI).

Check Digit Verification of cas no

The CAS Registry Mumber 423-55-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 423-55:
(5*4)+(4*2)+(3*3)+(2*5)+(1*5)=52
52 % 10 = 2
So 423-55-2 is a valid CAS Registry Number.

COMPOSITION CONTAINING C8F17Br AND METHOD FOR PRODUCING C8F17Br

-

Paragraph 0054-0057, (2020/06/08)

This invention provides a composition that contains PFOB with a PFOA content lower than that of known PFOB, and that is less likely to have an adverse effect on the environment; and provides a method for producing PFOB. The composition contains C8F17Brand further contains C7F15COOH, wherein C7F15COOH is present in a concentration of 25 ppb or less based on the total weight of C8F17Br. The method for producing C8F17Br comprises reacting C8F17I and a brominating agent to obtain C8F17Br, and alkali-washing the obtained C8F17Br to reduce the C7F15COOH content to 25 ppb or less based on the total weight of C8F17Br.

Viscoelastic compositions containing concentrated fluorinated compounds their method of preparation and their uses

-

, (2008/06/13)

Compositions for topical application in gel form comprising a fluorocarbon or perfluorocarbon compound or mixtures thereof at a concentration of at least about 75% v/v, a minor quantity of a surface active agent and an aqueous phase. The compositions provide a storage-stable high concentration fluorocarbon gel that is prepared without the use of thickeners or additional stabilizing agents. The gels are useful in formulations for pharmaceutical, cosmetic purposes and for other products as well.
