CAS :Produit contrôlé<p>22-Hydroxy-25-fluorocholesterol is a cholesterol acyltransferase inhibitor, which prevents the synthesis of cholesterol in the body. It is also used as a sequestering agent, preventing cholesterol from being absorbed into the body. This drug has been shown to decrease high cholesterol levels and oxysterols in patients with coronary artery disease. 22-Hydoxy-25-fluorocholesterol binds to cellular membranes and blocks the transport of bile acids and acid, thereby inhibiting cholesterol synthesis. It also inhibits inflammation by blocking inflammatory cytokines such as TNF-α and IL-1β. This drug may also be useful for treating inflammatory diseases such as asthma and rheumatoid arthritis due to its inhibition of leukotriene synthesis.</p>Formule :C27H45FO2Degré de pureté :Min. 95%Masse moléculaire :420.64 g/mol5-Fluorosalicylic acid
CAS :<p>5-Fluorosalicylic acid is a nonsteroidal anti-inflammatory drug that belongs to the group of 5-substituted salicylates. It has a strong affinity for human serum and can be used as an indicator in the determination of blood glucose. 5-Fluorosalicylic acid also binds to p-nitrophenyl phosphate with high affinity, which is involved in the regulation of cellular energy metabolism and plays a role in the production of ATP. The drug has been shown to form stable complexes with coumarin derivatives, which may have an effect on enzyme activities by modifying their conformational properties. 5-Fluorosalicylic acid has been shown to interact with other drugs, such as acetaminophen or ibuprofen, which may increase the risk of adverse effects.</p>Formule :C7H5FO3Degré de pureté :Min. 95%Couleur et forme :SolidMasse moléculaire :156.11 g/mol4,5-Dimethoxy-2-nitrocinnamic acid

CAS :<p>Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used to treat pain and inflammation. It belongs to the group of fatty acid derivatives, which are drugs that block the production of prostaglandins. Ibuprofen has been shown to have contraceptive effects in humans and experimental models, as well as an effect on human serum lipoproteins. Ibuprofen has also been shown to inhibit the synthesis of prostaglandins in rat liver microsomes and asymmetric synthesis in wastewater treatment. Its pharmacokinetic properties are determined by its absorption rate, distribution volume, and metabolism rate. The kinetic behavior of ibuprofen is affected by matrix effect and the kinetic behavior of ibuprofen is also affected by its pharmacokinetic properties such as isooctane, carcinoma cell lines, etc.</p>Formule :C13H18O2Degré de pureté :Min. 95%Couleur et forme :White PowderMasse moléculaire :206.28 g/mol2-Dicyclohexylphosphino-2',6'-dimethoxybiphenyl
CAS :<p>2-Dicyclohexylphosphino-2',6'-dimethoxybiphenyl is a fluorescent chemical that has been used to study interactions of fatty acids and halides. It is also used in the synthesis of palladium complexes, which have been shown to be effective for hydrogenation reactions. 2-Dicyclohexylphosphino-2',6'-dimethoxybiphenyl can be synthesized from 2,6-dichlorobenzaldehyde and dicyclohexylphosphine by the addition of trifluoroacetic acid. The synthesis proceeds via a substitution reaction with methoxy groups on the aromatic ring. This product fluoresces under ultraviolet light at 351 nm.</p>Formule :C26H35O2PDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :410.53 g/mol2-(2-naphthyloxy)ethanenitrile

CAS :<p>Magnesium aspartate dihydrate is a chemical compound that is used to treat high blood pressure and heart disease. It is a salt of magnesium and L-aspartic acid, which are both active substances in the drug. Magnesium aspartate dihydrate has been shown to have a treatment effect on elevated levels of c-reactive protein (CRP) in men with normal kidney function. The drug has also been shown to be effective for the treatment of cavity, although it does not work for everyone. Magnesium aspartate dihydrate is chemically stable and can be used for diagnosis of magnesium deficiency, but it should not be given to women who are pregnant or breast-feeding. This drug may also inhibit the action of proton pumps, which are found in the body's cells that produce stomach acid.</p>Formule :C8H12N2O8Mg·2H2OCouleur et forme :White PowderMasse moléculaire :324.53 g/mol2-Hydroxy-5-nitroacetophenone
CAS :<p>2-Hydroxy-5-nitroacetophenone is a synthetic molecule that has two functional groups. It is synthesized by reacting morpholine with malonic acid. 2-Hydroxy-5-nitroacetophenone is an electron donor, which means it can accept electrons from other molecules. This compound can be used as a diagnostic tool for cancer cells because it reacts with oxygen to form polyhedra, which are indicative of cancer senescence. In addition, this compound can be used to measure the concentration of plasma mass spectrometers by using electron spin resonance (ESR) and magnetic resonance imaging (MRI). The unpaired electrons on the nitro group of the molecule react with oxygen in the air to form polyhedra and give off characteristic signals in ESR and MRI. These signals are proportional to the concentration of unpaired electrons and therefore provide a quantitative measurement of 2-hydroxy-5 nitroacetophenone in solution.</p>Formule :C8H7NO4Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :181.15 g/mol
