Description
Nonafluorobutane-1-sulfonic acid, also known as perfluoro butyl sulfonate (PFBS), is a colorless liquid belonging to the perfluoroalkyl family of chemicals. It is a perfluoroalkanesulfonic acid where all hydrogens of the butyl group have been replaced by fluorines, making it a superacid. NONAFLUORO-1-BUTANESULFONIC ACID can be synthesized by reacting 1-iodononafluorobutane with sodium dithionite in the presence of sodium bicarbonate in acetonitrile/water. It is known for its ability to react violently with water and may be incompatible with strong oxidizers. Upon decomposition, it can form carbon oxides, sulfur oxides, and hydrogen fluoride.
Uses
Used in Stain Repellents:
Nonafluorobutane-1-sulfonic acid is used as a component in stain repellents for carpets and furniture, providing protection against various types of stains.
Used as a Flame Retardant:
Potassium perfluorobutane sulfonate, a specific form of the chemical, is being used as a flame retardant in place of brominated retardants, offering an alternative with reduced environmental impact.
Used as an Environmentally Friendly Substitute:
Nonafluorobutane-1-sulfonic acid is being used as a substitute for other perfluoroalkyl compounds because it is not believed to bioaccumulate in the environment, making it a more environmentally friendly option.
Used in Chemical Synthesis:
Nonafluorobutane-1-sulfonic acid may be used as a catalyst in the synthesis of 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin and N-benzylpyridin-2-amine, contributing to the development of new chemical compounds and materials.
Used in the Chemical Industry:
In the chemical industry, Nonafluorobutane-1-sulfonic acid is used as a superacid for various chemical reactions, taking advantage of its strong acidic properties to enhance reaction rates and selectivity.
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

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.

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.
