CAS :Produit contrôlé<p>22a-Hydroxycholesterol is a naturally occurring, oxygenated cholesterol metabolite. It binds to the transcriptional coactivator retinoid X receptor (RXR) and inhibits the activity of certain liver enzymes. 22a-Hydroxycholesterol has been shown to have toxic effects on mouse tumors and to inhibit the production of ATP in vitro. 22a-Hydoxycholesterol also inhibits the function of ATP binding cassette (ABC) transporter proteins, which are involved in cholesterol transport from cells. The long-term toxicity of 22a-hydroxycholesterol is not well understood, although it has been shown that this metabolite can induce autoimmune diseases in rats.</p>Formule :C27H46O2Degré de pureté :Min. 95%Masse moléculaire :402.65 g/molWhiskey lactone
CAS :<p>Whiskey lactone is an organic compound that belongs to the class of lactones. This sample preparation technique employs a solution of sodium hydroxide that acts as an extractant. The hydroxide solution reacts with the acidic ph of the sample, which causes hydrolysis and esterification of the fatty acid chains in the sample. The reaction is accompanied by a color change from yellow to blue. Whiskey lactone has been shown to have high values for eugenol and chemical structures such as isovaleric acid and hydroxyl group.</p>Formule :C9H16O2Degré de pureté :Min. 98 Area-%Couleur et forme :Clear LiquidMasse moléculaire :156.22 g/mol(R)-1,2,3,4-Tetrahydro-5-methoxy-N-propyl-2-naphthalenamine hydrochloride

CAS :<p>Naphthalen-2-ethanol is a primary alcohol that has been synthesized and immobilized onto boron nitride. It can be used as a synthetic reaction rate indicator. Naphthalen-2-ethanol is soluble in organic solvents such as methanol, which can be used to determine the concentration of methanol in solution by observing the change in absorbance at 230 nm. This compound has functional groups such as carbinols, which are characterized by their high reactivity and ability to form esters, ethers, amides, or nitriles. Naphthalen-2-ethanol also reacts with lipases to produce polyamines and with chromatography to produce substitutive nomenclature.</p>Formule :C12H12ODegré de pureté :Min. 95%Masse moléculaire :172.22 g/mol5,6,7,8-Tetrahydronaphthalene-1-carbaldehyde
