1763-23-1 Usage
Description
Heptadecafluorooctanesulfonic acid is a very useful catalyst in chemical industry. It can catalyze the Intramolecular Hydroamination of Olefinic Sulfonamides in Fluorous Biphase System (FBS)1. It can also catalyze ring-opening reactions of methylenecyclopropanes with aromatic amines, sulfonamides and alcohols in supercritical carbon dioxide2. It is useful in the nitroaldol reaction in fluorous media, which is an important improvement of the chemo-selective addition of aldehyde3.
Chemical Properties
Perfluorooctane sulfonate can exist as a liquid or a powder. It is soluble in water (NTP, 2013). Perfluorooctane sulfonate has the ability to react with strong oxidizing agents. Upon decomposition, PFOS can form carbon oxides, sulfur oxides, and hydrogen fluoride. Additional information related to the physical and chemical properties of PFOS are not currently available.
Uses
Different sources of media describe the Uses of 1763-23-1 differently. You can refer to the following data:
1. Perfluorooctane sulfonate (PFOS, 1-octanesulfonic acid, heptadecafluorooctanesulfonic acid, perfluorooctanesulfonic acid, 1-perfluorooctanesulfonic acid) is an eight-carbon compound in the perfluoroalkyl family of chemicals. Perfluorooctane sulfonate is used in a variety of applications, including textiles, leather products, cleaning products, and pesticides. Its main use was as a stain repellent on carpet, furniture, and other consumer products. 3M was the primary manufacturer of the chemical until it voluntarily phased it out in 2002 (USEPA, 2012). Perfluorooctane sulfonate is not manufactured any longer in the United States, but it can be imported for use in specific applications.
2. Heptadecafluorooctanesulfonic acid may be used as an analytical reference standard for the determination of the analyte in water samples using solid-phase microextraction combined with high-performance liquid chromatography with electrospray-ion trap mass spectrometry.

Check Digit Verification of cas no
The CAS Registry Mumber 1763-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1763-23:
(6*1)+(5*7)+(4*6)+(3*3)+(2*2)+(1*3)=81
81 % 10 = 1
So 1763-23-1 is a valid CAS Registry Number.

This study describes a synthesis of symmetric and dissymmetric bis[(perfluoroalkane)-sulfonyl]imides by the reaction of the sodium salt of perfluoroalkanesulfonamide RFSO2NH-Na + (RF = C4F9, C6F 13, C8F17) with hexamethyldisilazane and perfluoroalkanesulfonylfluoride RFSO2F (RF - C4F9, C6F13, C8F 17). They are obtained, in two steps, in moderate overall yield. Moreover, this paper provides a study of their inhibition on bovine carbonic anhydrase.
