Formule :C7D3HCl2O2Couleur et forme :NeatMasse moléculaire :194.036-Fluorovitamin D3
CAS :6-Fluorovitamin D3 is a synthetic analog of vitamin D3, which is a modified form of the naturally occurring hormone known as cholecalciferol. This molecule is typically derived through chemical synthesis, incorporating a fluorine atom at a specific position on the vitamin D3 structure. The introduction of the fluorine atom is designed to enhance the stability of the compound and potentially alter its biological activity.Formule :C27H43FODegré de pureté :Min. 95%Masse moléculaire :402.63 g/molAlbendazole-sulphone-D3
CAS :Albendazole-sulphone-D3 is an analyte that is extracted from a dispersive sulphoxide. It is extracted by an acetonitrile phase extraction and analyzed by liquid chromatography. Albendazole-sulphone-D3 has been shown to have anthelmintic properties, which are due to its ability to inhibit the synthesis of folic acid in nematodes. This drug binds to the acetylcholine receptor site on the worm's neuromuscular junction, preventing acetylcholine from accessing this site and causing paralysis. It has also been shown to be effective against roundworms (Ascaris lumbricoides), hookworms (Ancylostoma duodenale), and whipworms (Trichuris trichiura).Formule :C12H12D3N3O4SDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :300.35 g/mol25-Hydroxyvitamin D3 monohydrate
CAS :25-Hydroxyvitamin D3 monohydrate is a vitamin D analog that has been shown to reduce elevated levels of parathyroid hormone and improve bone mineral density. It is used for the treatment of chronic kidney disease, hyperparathyroidism, and osteoporosis. 25-Hydroxyvitamin D3 monohydrate has been found to be effective in the treatment of these conditions because it increases the body's production of calcitriol, the active form of vitamin D. Calcitriol promotes calcium absorption in the gut and reduces renal excretion of calcium by inhibiting parathyroid hormone synthesis. This drug also inhibits pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α.Formule :C27H44O2·H2ODegré de pureté :Min. 97 Area-%Couleur et forme :White PowderMasse moléculaire :418.65 g/mol22-Fluorovitamin D3
CAS :22-Fluorovitamin D3 is a synthetic analog of vitamin D3, which is derived from chemical synthesis involving fluorination at the C-22 position. This modification results in a compound that mimics the structure and activity of naturally occurring vitamin D3 but with altered pharmacokinetics and metabolic stability. The fluorine atom, due to its size and electronegativity, influences the binding affinity and activity of the compound at vitamin D receptors.Formule :C27H43FODegré de pureté :Min. 95%Masse moléculaire :402.63 g/molLeucocrystal Violet-d6
CAS :Produit contrôléLeucocrystal violet-d6 is a dye that has been used for decades as a fluorescent marker for chromatographic analysis. It is commonly used as an indicator to determine the purity of acetonitrile in analytical methods. Leucocrystal violet-d6 is prepared by dissolving the dye in acetonitrile and adding it to a test sample. The solvent is then evaporated and the dye will be left behind. Leucocrystal violet-d6 has a strong absorption band at approximately 605 nm, which can be detected using a spectrometer. The major limitation of this method is that it cannot be used to analyze samples containing water or organic solvents such as methanol or ethanol.Formule :C25D6H25N3Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :379.57 g/mol5-(Hydroxymethyl)-2’-deoxycytidine-d3

CAS :Produit contrôléDiethylstilbestrol-d8 is a synthetic estrogen that is used as an analytical standard for the detection of 17β-estradiol and estrone. Diethylstilbestrol-d8 has been used to monitor the synthesis of estrogens in human tissues and to measure the effects of estrogen on target cells. It has been shown that this compound binds to the estrogen receptor, which mediates its effects in a similar manner as natural estrogens. Diethylstilbestrol-d8 is also used to determine if the estrogen receptors are present in a sample. This can be done by measuring the response of cells to diethylstilbestrol-d8 or by measuring its binding to any receptor sites in a sample. Diethylstilbestrol-d8 has also been shown to have anti-inflammatory properties, which may be due to its inhibition of prostaglandin synthesis.Formule :C18H12D8O2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :276.4 g/mol4-Bromofluorobenzene-D4

CAS :Vitamin D2 is a fat-soluble vitamin that is required for the absorption of calcium and phosphate. It can be obtained through dietary supplements or by exposure to sunlight. Vitamin D2 is a prohormone that needs to undergo two hydroxylation reactions in the liver and kidney before it becomes the active form, calcitriol. Vitamin D2 has been shown to have beneficial effects on bone mineralization and phosphatase activity, as well as an inhibitory effect on the production of parathyroid hormone. Hydroxyapatite, a component of bone tissue, has been shown to react with vitamin D2 in vitro, which may be due to its ability to act as an additive or stabilizer.END>>
