2(5H)-Thiophenone, 3-hydroxy-4-methyl-

Description:

2(5H)-Thiophenone, 3-hydroxy-4-methyl- is an organic compound characterized by its thiophene ring structure, which is a five-membered aromatic heterocycle containing sulfur. This compound features a ketone functional group (the thiophenone part) and a hydroxyl group (–OH) along with a methyl group (–CH3) on the aromatic ring. The presence of these functional groups contributes to its chemical reactivity and potential applications in various fields, including pharmaceuticals and organic synthesis. The hydroxyl group can participate in hydrogen bonding, influencing the compound's solubility and boiling point. Additionally, the methyl group can affect the electronic properties of the molecule, potentially enhancing its reactivity or stability. As with many thiophene derivatives, this compound may exhibit interesting biological activities, making it a subject of interest in medicinal chemistry. Its specific properties, such as melting point, boiling point, and spectral characteristics, would require further investigation through experimental data or literature for precise applications and behavior in chemical reactions.

Cefradine impurity F

CAS: 34876-35-2

Cefradine impurity F is a hydrolysis product of cefradine, which is an antibiotic. It is catalysed by β-lactamase enzymes and undergoes nucleophilic attack on the carbon atom adjacent to the carbonyl group. Cefradine impurity F has been shown to be effective against enterobacter, which is a type of bacteria that can cause urinary tract infections. The uptake of cefradine impurity F into bacteria can occur through passive diffusion or active transport mechanisms. This drug was also found to be hydrolyzed by buffers such as phosphate and acetate in vitro, but not by other substances such as EDTA and citrate. Cefradine impurity F has been shown to be hydrolyzed in vivo, with the most likely mechanism being spontaneous hydrolysis.
