375-73-5 | Perfluorobutanesulfonic acid

CAS:375-73-5 | Perfluorobutanesulfonic acid ,Description

Perfluorobutanesulfonic acid (PFBS) is a fluorosurfactant, an organic compound with a wide range of uses in industry and in scientific research. It is a perfluoroalkylsulfonate, a family of compounds with a unique combination of properties that make them particularly useful in areas such as lubrication, detergency, and surface protection. In addition, PFBS is increasingly being used in scientific research due to its unique chemical and physical properties, which make it a good model for studying a variety of biological processes. 
 

Scientific Research Applications

1. Water Treatment Challenges and Solutions

PFBS, a short-chain perfluorinated alkyl substance (PFAS), is noted for its resistance to oil, water, chemicals, and heat, leading to extensive industrial use. However, its removal from water poses significant challenges. Conventional water treatment methods like flocculation, sedimentation, or biodegradation are ineffective against PFAS compounds, including PFBS. Recent advances in materials research have highlighted the potential of thin-film composite (TFC) membranes for efficient PFBS removal from water, garnering significant attention in scientific circles (Nadagouda & Lee, 2021).

2. Environmental Contamination and Detection Methods

PFBS, as part of the perfluorinated acids class, has been detected in various marine environments. A reliable and highly sensitive analytical method capable of detecting PFBS at low levels in oceanic waters has been developed, contributing to understanding the distribution and fate of PFBS in marine ecosystems (Yamashita et al., 2004).

3. (Eco)Toxicity Assessment Framework

A novel framework for characterizing PFBS in life cycle impact assessment (LCIA) has been proposed. This framework aims to translate emissions of primary emitted PFASs into their persistent degradation products, like PFBS, allowing for the calculation of characterization factors for human toxicity and aquatic ecotoxicity. Despite data limitations, this framework plays a crucial role in assessing the long-term environmental and health impacts of PFBS and other PFASs (Holmquist et al., 2020).

4. Human Health Impact Studies

Studies have investigated the presence of PFBS in human samples, providing insights into its distribution and potential health impacts. Research focusing on the concentration and distribution profiles of PFBS and other PFASs in human blood samples highlights the importance of understanding exposure patterns and their implications for human health (Yeung et al., 2006).

5. Rapid Sensing Approaches

Research on the detection of PFBS through voltammetry at micro-interfaces between immiscible electrolyte solutions (μITIES) indicates a potential for rapid sensing of PFBS in environmental samples. This method provides a basis for developing new sensing strategies for PFBS and other PFAS compounds (Islam & Arrigan, 2022).
