375-73-5 Usage
Chemical Properties
Nonafluorobutane-1-sulfonic acid is a colorless liquid. Perfluoro butyl sulfonate has the ability to react violently with water, so preventing exposure tomoisture should be a priority. It may also be incompatible with strong oxidizers. Upon decomposition, PFBS can form carbon oxides, sulfur oxides, and hydrogen fluoride.
Uses
Different sources of media describe the Uses of 375-73-5 differently. You can refer to the following data:
1. Perfluoro butyl sulfonate (PFBS, nonafluoro-1-butanesulfonic acid, perfluorobutane sulfonic acid, 1-perfluorobutane sulfonic acid) is a four-carbon compound in the perfluoroalkyl family of chemicals. It can be found in stain repellents used for carpets and furniture. A specific form of the chemical, potassium perfluorobutane sulfonate, is being used as a flame retardant in place of brominated retardants. Perfluoro butyl sulfonate is being used as a substitute for other perfluoroalkyl compounds because it is not believed to bioaccumulate in the environment.
Nonafluorobutane-1-sulfonic acid can be considered as a superacid, which can be synthesized by reacting 1-iodononafluorobutane with sodium dithionite in the presence of sodium bicarbonate in acetonitrile/water.
Nonafluorobutane-1-sulfonic acid may be used as catalyst in the synthesis of 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin and N-benzylpyridin-2-amine.
2. Nonafluorobutane-1-sulfonic acid may be used as catalyst in the synthesis of 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin and N-benzylpyridin-2-amine.
Definition
ChEBI: A perfluoroalkanesulfonic acid that is butane-1-sulfonic acid in which all of the hydrogens of the butyl group have been replaced by fluorines.
General Description
Nonafluorobutane-1-sulfonic acid can be considered as a superacid, which can be synthesized by reacting 1-iodononafluorobutane with sodium dithionite in the presence of sodium bicarbonate in acetonitrile/water.
Safety Profile
A poison by ingestion.When heated to decomposition it emits toxic vapors of SOx and Clí.
Environmental Fate
Perfluoro butyl sulfonate is embedded into the carpet and furniture to offer protection against stains and spills. It is also applied to various household products as it may play a role in the retarding of flames during a fire. Over time as furniture, carpet, and other household products begin to degrade, the chemical may be introduced into the indoor environment in house dust. Perfluoro butyl sulfonate, along with other perfluoroalkyl compounds, has been detected in house dust samples indicating a potential route for exposure for occupants (Strynar and Lindstrom, 2008). Frequent vacuuming and dust removal can prevent buildup of the contaminant in household dust and the indoor environment. Perfluoro butyl sulfonate can also be found in water systems as a result of human waste streams. Samples of tap water collected in China, Japan, India, the United States, and Canada, all contained detectable levels of PFBS (Mak et al., 2009). While the chemical has been detected in both the indoor environment and drinking water, the lack of toxicological data related to PFBS makes it hard to determine what levels of exposure are acceptable.
Check Digit Verification of cas no
The CAS Registry Mumber 375-73-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 375-73:
(5*3)+(4*7)+(3*5)+(2*7)+(1*3)=75
75 % 10 = 5
So 375-73-5 is a valid CAS Registry Number.

New and easily accessible nitrogen acyclic gold(I) carbenes: Structure and application in the gold-catalyzed phenol synthesis as well as the hydration of alkynes

, p. 1315 - 1337 (2010)
A series of gold(I) isonitrile complexes were prepared and converted to the corresponding diaminocarbene gold(I) complexes by reactions with primary and symmetrical secondary amines. Twelve crystal structure analyses of the gold(I) complexes could be obtained, in addition NMR studies allowed an analysis of the different diastereomers present in solution. In the gold-catalyzed phenol synthesis these complexes were very successful as pre-catalysts, reaching an unprecedented 3050 turnovers with a problematic substrate. Good conversions in the hydration of phenylacetylene could also be achieved.
Synthesis of symmetric and dissymetric bisperfluoroalkanesulfonylimides and evaluation of their inhibition on bovine carbonic anhydrase

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.
