Pigment orange 13, technical grade
CAS:Please enquire for more information about Pigment orange 13, technical grade including the price, delivery time and more detailed product information at the technical inquiry form on this pageFórmula:C32H24Cl2N8O2Forma y color:PowderPeso molecular:623.49 g/molC.I.Food Red 9:1
CAS:C.I.Food Red 9:1 is a synthetic red colorant that is used in food and other products such as cosmetics and pharmaceuticals. It is a synthetic pigment that can be prepared by the condensation of anthraquinone with glyoxal or glutaraldehyde followed by acid hydrolysis. The average molecular weight of C.I.Food Red 9:1 is about 1,500 Daltons.Pureza:Min. 95%Pigment Yellow 138;3,4,5,6-Tetrachloro-N-[2-(4,5,6,7-tetrachloro-2,3-dihydro-1,3-dioxo-1H-inden-2-yl)-8-Quinolyl]phthalimide
CAS:Pigment Yellow 138 is a polycarboxylic acid with the chemical formula C8H6Cl4O2. Pigment Yellow 138 has a molecular weight of 434.07 and can be used as a yellow pigment in paint, plastics, and textiles. Pigment Yellow 138 has an acidic pH and can be prepared by reacting phthalic anhydride with sodium hydroxide in aqueous solution to produce the sodium salt of pigment yellow 138. Pigment Yellow 138 is also soluble in hydroxide solutions, which makes it an excellent cross-linking agent for polymers. The color of pigments depends on the size of their particles; pigments with larger particle sizes are more opaque than those with smaller particle sizes.Fórmula:C26H6Cl8N2O4Pureza:Strengh Min 95%.Peso molecular:693.96 g/molC.I. Solvent blue 19
CAS:C.I. Solvent blue 19 is an azo dye that is used as a colorant in analytical chemistry and as a sample preparation reagent for organic compounds. C.I. Solvent blue 19 is used to measure the thermal expansion of polymers, such as polyethylene, polypropylene, and polystyrene. It is also used in the determination of total nitrogen content in samples by combustion analysis or other methods. The carcinogenic potential of C.I. Solvent blue 19 has been studied using animal models and cellular cultures, but it has not been found to cause cancer under these conditions. Cationic surfactants are effective at removing this dye from wastewater treatment systems and may be used for bladder infections due to its antibacterial properties against E-coli bacteria. C.I. Solvent blue 19 is prepared by reacting p-hydroxybenzoic acid with aniline and nitrobenzene in the presence of hydrochloric acid orFórmula:C21H16N2O2Pureza:Min. 95 Area-%Forma y color:Blue PowderPeso molecular:328.36 g/molCresol red
CAS:Cresol red is a weak diacidic molecule and an anionic dye largely used in genetic and biochemical studies. Cresol red is commonly used to measure the pH of aqueous solutions also from environmental samples, e.g. seawater (Byrne, 1989). Cresol red shows an increased protonation in acidic water-based solutions at low temperatures (Heger, 2006). Cresol red can be used to introduce pH-sensing features to sensing materials, such as, optical fibres or nanoparticles (Islam, 2021).Fórmula:C21H18O5SForma y color:Brown Red PowderPeso molecular:382.43 g/molPigment Yellow 42 (Technical Grade)

CAS:Ethyl Red Indicator is a chemical species that exhibits fluorescing properties under the influence of radiation. It is used as a test compound in analytical chemistry to determine the presence of acidic or basic compounds in a solution. Ethyl Red Indicator has been shown to react with quinoline derivatives and form an active methylene group, which facilitates electron transfer. This reaction mechanism leads to an enhancement of fluorescence intensity. The rate of the reaction can be determined by measuring the time taken for the ethyl red indicator to change from red-orange to pink.Fórmula:C17H19N3O2Pureza:Min. 95%Peso molecular:297.35 g/molRef: 3D-FE52636

CAS:Producto controlado6b-Hydroxy prednisolone is a metabolite of prednisolone. The metabolism of prednisolone to 6b-hydroxy prednisolone is catalyzed by the enzyme CYP3A4, which results in the formation of 6β-hydroxyprednisolone and a hydrogen peroxide that reacts with catalase to form water and oxygen. The conversion is dependent on the concentration of galactose, as it provides substrate for CYP3A4. If cyclosporine or other drugs are taken concurrently, they may inhibit the metabolism of 6b-hydroxy prednisolone. The kinetics of 6β-hydroxyprednisolone have been investigated in tissues and plasma samples, and it has been shown that this metabolite has a short half-life in both tissues and plasma samples. This drug can be analysed using chromatography, but endogenous substances such as cortisol can interfere with the process.Fórmula:C21H28O6Pureza:Min. 95%Forma y color:Light (Or Pale) Yellow SolidPeso molecular:376.44 g/mol
