2,4-Difluoro-5-nitrobenzene sulfonic acid is an aromatic sulfonic acid characterized by the presence of both fluorine and nitro substituents on the benzene ring. The compound features two fluorine atoms located at the 2 and 4 positions, and a nitro group at the 5 position, along with a sulfonic acid group (-SO3H) that is typically found at the para position relative to the nitro group. This structure imparts significant polarity and solubility in polar solvents, making it useful in various chemical applications. The presence of the sulfonic acid group enhances its acidity, allowing it to participate in acid-base reactions. Additionally, the fluorine atoms contribute to the compound's stability and reactivity, influencing its behavior in electrophilic aromatic substitution reactions. Due to its unique functional groups, 2,4-difluoro-5-nitrobenzene sulfonic acid can serve as an important intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals. Safety precautions should be observed when handling this compound, as it may pose health risks due to its acidic nature and potential toxicity.

2,4-Difluoro-5-nitrobenzenesulfonic acid (DFNS) is a sulfonate with potassium that acts as a cross-linking agent for proteins. It can be used to produce cross-linked protein samples for analysis by spectroscopic methods. DFNS has been shown to increase the stability of lysozyme in solution and to cross-link lysozyme molecules together, which may be useful for studying the molecular structure of lysozyme.
