Tetrahydrofuran-2,3,4,5-tetracarboxylic acid
CAS:Tetrahydrofuran-2,3,4,5-tetracarboxylic acid (THF-TTCA) is a polycarboxylic acid that can be extracted from coal tar. It has a number of uses as an extractant in the production of polycarbonates and other plastics. Tetrahydrofuran-2,3,4,5-tetracarboxylic acid has been shown to crystallize from solution at high temperatures and pressures. The crystal structure of THF-TTCA consists of a ring of six carboxylate groups with three molecules of water coordinating to form hydrogen bonds. Tetrahydrofuran-2,3,4,5-tetracarboxylic acid has the structural analog of the metal ion tetraammineborane (NHBH). This compound is acidic and binds strongly to metal ions such as copper(II) or cobalt(IIIFórmula:C8H8O9Pureza:Min. 95%Peso molecular:248.14 g/mol5-Ethoxy-2(5H)-furanone
CAS:5-Ethoxy-2(5H)-furanone is an oxidation product of 5-ethoxy-2(5H)-furanone. It has an isomeric, stereospecific, regiospecifically, and a tautomeric relationship with furfural. 5-Ethoxy-2(5H)-furanone can be produced by the oxidation of furfural with boron trifluoride etherate in the presence of iodosobenzene. The reaction mechanism involves the addition of hydrogen peroxide to the boron trifluoride etherate to form hydroperoxydiborane. This compound then reacts with iodosobenzene to produce 5-ethoxy-2(5H)-furanone and 2,5-dihydroxybenzaldehyde. The reaction produces a mixture of diastereomers that contain different numbers of carbon atoms due to the regiospecific

CAS:Dantrolene is an experimental model for malignant hyperthermia, a rare genetic condition that can cause muscle rigidity and death. Dantrolene has been shown to inhibit the activity of the dinucleotide phosphate (NADH) dehydrogenase enzyme in muscle cells. In addition, it inhibits calcium release from the sarcoplasmic reticulum and activates ryanodine receptors. Dantrolene also inhibits muscle contractions and prevents neuronal death by inhibiting the release of glutamate.Fórmula:C14H10N4O5Pureza:Min. 95%Forma y color:SolidPeso molecular:314.25 g/molParthenolide

CAS:5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone is a colorless liquid that has a fruity, sweet odor. It is used in the manufacture of flavors and fragrances. 5-Ethyl-4-hydroxy-2-methyl-3(2H)-furanone can be obtained by the reaction of butanedione with dilute sulfuric acid, followed by treatment with an absorber containing propylene glycol and 4-ethyl-2methoxyphenol. The product is then treated with radiation energy to produce furfural, which reacts with anthranilate to form methyl anthranilate. Methyl anthranilate can be converted into phenylmethyl by reacting it with glycosidase.
