CAS:1,2-Dihydrobenzene (1,2-DH) is a molecule that has the chemical formula C6H6. It is a colorless liquid with boiling point of 147°C and melting point of -11°C. 1,2-DH has been shown to form hydrogen bonds with water molecules. This compound is also insoluble in water, which may be due to its dehydrating properties. When catalyzed by an acid or base, 1,2-DH undergoes dehydration reactions. Acidic or basic conditions are required for this reaction to occur and the resulting product can be determined by x-ray diffraction studies. 1,2-DH has been shown to form coordination complexes with metal ions such as copper (Cu) and zinc (Zn). These complexes have been shown to have ligand binding properties that lead to supramolecular structures. Intermolecular hydrogen bonding interactions between 1,2-DH molecules have also been observed duringFórmula:C9H12OPureza:Min. 95%Peso molecular:136.19 g/mol5-Hydroxyquinolin-2(1H)-one

CAS:The 2-hydroxyphenyl-3-phenylpropenal (HPPA) is a fatty acid with a hydroxyl group. It has been shown to have anti-inflammatory properties and inhibit the production of TNF-α in mice. HPPA is synthesized by the oxidation of oleic acid, which can be catalyzed by a number of different enzymes such as lipoxygenases, cyclooxygenases, or cytochrome P450s. The synthesis can also be inhibited by other substances such as dibromides or tnf-α. HPPA also has potent inhibitory activity against transcription polymerase chain reaction and protein synthesis. This inhibition is due to its carbonyl group that reacts with the intramolecular hydrogen on the enzyme's active site. The reaction mechanism for this inhibition is similar to that of propranolol, another drug used for treatment of inflammatory diseases.Fórmula:C15H12O2Pureza:Min. 95%Forma y color:PowderPeso molecular:224.25 g/mol2-(Chloromethyl)-3-(3-methylphenyl)quinazolin-4(3H)-one
