The environmental impact and metabolic fate of chemical compounds are critical considerations in modern chemistry and toxicology. While 2-Fluoroethanol (CAS: 371-62-0) itself is not typically a primary industrial emission, its significance arises from its role as a metabolite, most notably of the hydrochlorofluorocarbon (HCFC) 1,1-dichloro-1-fluoroethane (HCFC-141b). Understanding these pathways is crucial for environmental risk assessment and biomonitoring.

In biological systems, HCFC-141b undergoes biotransformation, often catalyzed by cytochrome P450 enzymes, leading to the formation of 2-Fluoroethanol. Following its formation, this alcohol is commonly conjugated with glucuronic acid, forming 2-fluoroethyl glucuronide. This conjugate is more water-soluble and less toxic, facilitating its excretion from the body, typically via urine. The study of these metabolic processes is often conducted using analytical techniques such as GC-MS and ¹⁹F NMR to identify and quantify these metabolites in biological samples.

From an environmental perspective, the atmospheric degradation of HCFC-141b, its precursor, is a key factor. The primary degradation mechanism in the troposphere involves reactions with hydroxyl (OH) radicals. This process leads to the formation of inorganic acids like HCl and HF, as well as CO₂. While 2-Fluoroethanol can be formed as an intermediate, its physical properties—lower volatility and higher water solubility compared to HCFC-141b—suggest that if released directly into the environment, it would preferentially partition into aqueous phases rather than the atmosphere. This limits its potential for atmospheric transport and ozone depletion compared to its volatile precursor.

The environmental fate of degradation products, such as potential acids formed from further oxidation of 2-Fluoroethanol, is also considered. However, the contribution of these pathways to environmental issues like acid rain is generally not considered significant at current emission levels. The study of these metabolic and environmental transformations highlights the interconnectedness of chemical compounds and their impact on both biological and abiotic systems.
