C.I.Vat Orange 15
CAS :<p>C.I. Vat Orange 15 is a polymerization inhibitor that prevents polymerization by reacting with the hydrogen peroxide, which is generated during the chemical reaction. The addition of C.I. Vat Orange 15 to a polymerization system will slow down the reaction and increase the yield of the desired product. This chemical can also be used in organic solvents and a variety of other reactions, such as light resistance and surfactant production. It is not soluble in water and requires an organic solvent for use in coatings or resins, but it does not react with esters or ethers. C.I. Vat Orange 15 has been shown to have high concentrations, but it is not toxic to animals or humans.>>END>></p>Degré de pureté :Min. 95%16a-Hydroxyprednisolone
Produit contrôlé<p>16a-Hydroxyprednisolone is a synthetic corticosteroid that has been used in the treatment of inflammatory diseases. It has a potency of 1/10th that of prednisolone and is used as an industrial preparation, such as for the production of plastics. 16a-Hydroxyprednisolone is prepared by reacting phthalic anhydride with hydrocortisone or hydrocortisone acetate.
