It has a melting point range of 251-255°C, with decomposition. It is soluble in glacial acetic acid, but only slightly soluble in methanol, acetone, and DMF. It is extremely difficult to dissolve in water, ethanol, and chloroform, and is insoluble in benzene. However, it can be dissolved in dilute alkali or acid solutions.

용도Pipemidic acid is a quinolone antibacterial drug that is primarily used to treat gram-negative infections of the urinary tract. It is also an antibiotic and cell selection agent. Unlike nalidixic acid, pipemidic acid has a broader spectrum of antibacterial activity and is effective for treating urinary tract and ENT infections.
일반 설명Chemical structure: quinolone
The synthesis of pipemidic acid involves a series of steps. First, ethyl 2,4-dichloropyrimidine-5-carboxylate is condensed and cyclized with ethyl β-ethylaminopropionate to yield 2-chloro-5-hydroxy-7,8-dihydro-8-ethylpyridine[2,3-d]pyrimidine-6-carboxylate. This compound is then brominated and subsequently condensed with piperazine. The resulting product is hydrolyzed and neutralized to obtain pipemidic acid.

정의ChEBI: Pipemidic acid is a pyridopyrimidine that is 5-oxo-5,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylic acid substituted at position 2 by a piperazin-1-yl group and at position 8 by an ethyl group. A synthetic broad-spectrum antibacterial, it is used for treatment of gastrointestinal, biliary, and urinary infections. It has a role as an antibacterial drug and a DNA synthesis inhibitor. It is a monocarboxylic acid, an amino acid, a N-arylpiperazine, a pyridopyrimidine and a quinolone antibiotic.
