CAS:<p>2'-Hydroxy-2,4,4',6'-tetramethoxychalcone (HTMC) is a bioactive substance that has been shown to have anticancer properties. HTMC has been shown to have allopathic effects in a statistically significant manner and has been used in traditional herbal medicine for centuries. The mechanisms of action are not well understood but may be due to its ability to inhibit the activity of arjunic acid and flavonoids. HTMC is found in plants such as tropical trees and herbs from India, including Acacia catechu and Tinospora cordifolia. It also has pharmacological properties, which may be due to its derivates that are isolated from these plants. HTMC shows no adverse effects on humans when taken orally at doses up to 1 g/day for 28 days.</p>Fórmula:C19H20O6Pureza:Min. 95%Cor e Forma:PowderPeso molecular:344.36 g/mol1-(2-Thiazolylazo)-2-naphthol
CAS:<p>1-(2-Thiazolylazo)-2-naphthol is a fluorescent dye that is used in analytical chemistry, cell culture, and flow cytometry. It has been shown to be useful for the detection of cancer cells.

CAS:<p>Octakis(trimethylsiloxy)silsesquioxane is a cross-linking agent that forms covalent bonds with ethylene diamine and aluminium ions. It has been shown to be active against bacterial species such as Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. Octakis(trimethylsiloxy)silsesquioxane binds to the calcium carbonate of the cell wall, forming a complex that prevents the bacteria from adhering to surfaces. The fluidity of octakis(trimethylsiloxy)silsesquioxane particles allows them to penetrate the cell membrane and inhibit protein synthesis by binding to ribosomes. Octakis(trimethylsiloxy)silsesquioxane can also be used as an encapsulation agent for drugs in order to prevent their degradation by enzymes in the gastrointestinal tract.</p>Fórmula:C24H72O20Si16Pureza:Min. 95%Cor e Forma:Clear LiquidPeso molecular:1,130.18 g/molRivastigmine tartrate

CAS:<p>2,6-Dimethoxynaphthalene is a skeleton that belongs to the naphthalene class of compounds. It is a white crystalline solid that is soluble in organic solvents. This compound has been used as an intermediate for the synthesis of dyes and pharmaceuticals, but it is most commonly used as a precursor to reactive carboxylic acid derivatives. The sulfonation of 2,6-dimethoxynaphthalene with SO3 leads to the formation of ethyl diazoacetate and subsequent acylation reactions can be used to produce esters. The reaction mechanism for these reactions involves proton transport from the sulfur atom to the oxygen atom on ethyl diazoacetate. Supramolecular chemistry studies have shown that this reaction also takes place at low temperatures without the need for an acid catalyst.</p>Fórmula:C12H12O2Pureza:Min. 98 Area-%Peso molecular:188.22 g/mol
