4-(Phenylamino)benzoic acid

Description:

4-(Phenylamino)benzoic acid, also known as PABA (para-aminobenzoic acid), is an aromatic amine and a derivative of benzoic acid. It features a phenylamino group attached to the para position of the benzoic acid moiety, which contributes to its unique chemical properties. This compound typically appears as a white to off-white crystalline solid and is soluble in organic solvents like ethanol and dimethyl sulfoxide, but has limited solubility in water. Its molecular structure includes both an amino group and a carboxylic acid group, allowing it to participate in various chemical reactions, including acylation and amidation. 4-(Phenylamino)benzoic acid is often utilized in the synthesis of dyes, pharmaceuticals, and as a UV filter in sunscreens due to its ability to absorb ultraviolet light. Additionally, it has applications in the field of biochemistry, particularly in studies related to folic acid metabolism. Safety data indicates that it should be handled with care, as it may cause skin and eye irritation upon contact.

4-(Phenylamino)benzoic acid (4-PABA) is a nonsteroidal anti-inflammatory drug that blocks the production of prostaglandins. It has been shown to inhibit the activity of intramolecular hydrogen, which is responsible for the formation of hydrochloric acid in the stomach. 4-PABA also binds to carboxylate and fatty acids in the body, which may account for its ability to treat chronic bronchitis. 4-(Phenylamino)benzoic acid has an apoptotic effect on cancer cells, leading to cell death by irreversible inhibition of DNA synthesis. This natural compound also binds to receptors and inhibits tryptophan fluorescence.
