Controlled Product16a-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. Impurities are removed by preparative thin-layer chromatography using silica gel plates. The product can be purified further by recrystallization from water or from chloroform/methanol mixtures. The presence of virulent microorganisms can be detected by adding a small amount to tissue samples and then examining them for signs of lysis or death. Acid catalysis is required in the sample preparation, which involves the use of an inorganic acid (e.g., hydrochloric acid) to remove any tracesFormula:C21H28O6Purity:Min. 98 Area-%Color and Shape:White PowderMolecular weight:376.44 g/molC.I.Disperse Orange 89

CAS:Malachite green oxalate is an adsorbent that can be used for wastewater treatment. It has a high affinity for organic molecules, which allows it to remove the substances from water. Malachite green oxalate reacts with the dissolved organic molecules and forms a strong bond with them, which prevents them from being redeposited in the water. The reaction mechanism of malachite green oxalate is based on its ability to adsorb onto the surface of organic molecules and react with them. The Langmuir adsorption isotherm shows that malachite green oxalate has a significant cytotoxicity and toxicological effect on human cells. Malachite green oxalate also binds to p-nitrophenyl phosphate (PNPP) in human serum, which is an enzyme substrate that is involved in many metabolic processes such as glycolysis and gluconeogenesis. The optical sensor was used to measure the redox potential of malachite green
