2-(4′-Hydroxyphenylazo)benzoic acid

Description:

2-(4′-Hydroxyphenylazo)benzoic acid, also known as a type of azo compound, is characterized by its azo functional group (-N=N-) linking two aromatic rings, specifically a benzoic acid moiety and a phenolic group. This compound typically exhibits a bright color due to the presence of the azo linkage, which is a common feature in many dyes and pigments. It is soluble in organic solvents and may have limited solubility in water, depending on the pH. The hydroxyl group on the phenyl ring can participate in hydrogen bonding, influencing its solubility and reactivity. This compound may also exhibit various chemical properties such as acidity due to the carboxylic acid group, and it can undergo reactions typical of aromatic compounds, including electrophilic substitution. Additionally, it may have applications in dye chemistry, analytical chemistry, and as a potential indicator due to its color change properties in different pH environments. Safety data should be consulted, as azo compounds can sometimes be associated with toxicity or environmental concerns.

2-(4-Hydroxyphenylazo)benzoic acid is a molecule that is used in the production of human immunoglobulin. It is activated with fatty acids and oligosaccharides to form a complex, which can be detected using confocal microscopy. The matrix-assisted laser ablation technique was used to determine the chemical structures and hydrogen bonding interactions of this molecule. 2-(4-Hydroxyphenylazo)benzoic acid has been shown to inhibit microbial infections by binding to the sodium salt form of Streptavidin, which inhibits bacterial growth. This molecule also has been used as an indicator for trifluoroacetic acid, which can be used as a sample preparation reagent.
