The reaction solution should be neutralized with sodium hydroxide and then hydrogenated using sodium dithionite or sodium sulfite. 3-Nitrosalicylic acid has been shown to inhibit the corrosion of metal surfaces and to function as an effective dose in the synthetic pathway for polymers.<br>3-Nitrosalicylic acid has high concentrations around pH 9.5, which can be reduced by electrochemical impedance spectroscopy (EIS).</p>Fórmula:C7H5NO5Pureza:Min. 95%Cor e Forma:PowderPeso molecular:183.12 g/molWilforlide A
CAS:<p>Wilforlide A is a novel anticancer drug that inhibits the growth of cancer cells by inhibiting amino transferase and blocking the synthesis of DNA. Wilforlide A has synergistic effects when used in combination with tripterygium wilfordii, a Chinese herb, and moronic acid, an extract from Tripterygium wilfordii. Wilforlide A also has anti-inflammatory properties and can be used to treat autoimmune diseases. The efficacy of Wilforlide A was evaluated using surface methodology on human skin squamous carcinoma samples. It was found that Wilforlide A had no cytotoxicity when applied to these cells. In addition, it inhibited tumor growth in mice inoculated with human squamous carcinoma cells. These findings show that Wilforlide A is a potential candidate for treating squamous carcinoma patients.</p>Fórmula:C30H46O3Pureza:Min. 95%Cor e Forma:PowderPeso molecular:454.68 g/mol2-Methoxycinnamic acid

CAS:<p>L-Allothreonine is a diagnostic agent that can be used to measure the glomerular filtration rate. It is a substrate molecule for the enzymes alloproteinase and threoninase, which hydrolyze it into L-serine and dicarboxylic acid. The reaction mechanism of L-allothreonine with malonic acid has been studied at different pH values by measuring the thermal expansion coefficient. L-Allothreonine is an intramolecular hydrogen donor in polymerase chain reactions, which leads to cyclic peptide formation. The enzyme activities of alloproteinase, threoninase, and cyclooxygenase have been studied in vitro using kinetic methods. L-Allothreonine is a natural amino acid that can be found in animal sources such as fish, meat, eggs, milk, yogurt, cheese and whey protein supplements.
