C.I.Food Yellow 4:1
CAS :Tartrazine is a yellow dye that belongs to the group of nonsteroidal anti-inflammatory drugs. It is used in the food industry as a colorant and has been used in many other products, such as medicines, cosmetics, and household goods. Tartrazine has been shown to be an agonist for the P2Y receptor and also inhibits the production of prostaglandin E2 by inhibiting phospholipase C activity. This drug has been shown to have anti-inflammatory effects in mouse models of inflammatory diseases.Formule :C48H33AlN12O27S6Degré de pureté :Min. 95%Masse moléculaire :1,429.2 g/molDisperse blue 60, technical grade dye content
CAS :Disperse Blue 60 is a stilbene-based dye that absorbs ultraviolet light and emits red fluorescent light. It is used in wastewater treatment, biological treatment, and supercritical water oxidation processes. Disperse Blue 60 is activated by fatty acid, alkanoic acid, or polymeric matrix to form an antimicrobial agent that can be used in radiation sterilization of food products. This dye also has the ability to absorb radiation in the range of 200 - 300 nm and emit fluorescence at 590 nm.

CAS :Pigment Yellow 147 is a yellow pigment, usually used in coatings and polycarbonates. It has a particle size of 0.1-2 microns and can be synthesized by polymerization of an aromatic hydrocarbon with a hydroxyl group and an inorganic compound that contains at least one functional group. Pigment Yellow 147 is also known as 3-hydroxybenzidine or 3-hydroxy-5-(o-chlorophenyl)-1,3-dihydrobenzindole. Pigment Yellow 147 absorbs light in the visible spectrum between 500 nm to 520 nm and has an index of refraction between 1.621 to 1.632 at 20°C, with a melting point of around 190°C. This pigment's color is due to the presence of microspheres that are typically composed of hydrogen chloride gas or another halogenated hydrocarbon such as tetrachloroethylene or hexachlorobenzene.Formule :C37H21N5O4Degré de pureté :Min. 95%Masse moléculaire :599.59 g/molAf488-alkyne

CAS :Pigment Red 21 is a primary amine that has a liquid crystal composition. It is used as a pigment in paints and plastics, and can be found in deionized water. Pigment Red 21 has a diameter of 10 nm and the structural formula C12H17N3O5. It is an inorganic pigment with chelate ligand functional groups. Pigment Red 21 is also known as Scarlet, FD&C Red No.21, or E120. This pigment absorbs radiation from the electromagnetic spectrum and converts it to heat energy, which causes its color change from red to orange when heated above its melting point of about 250 degrees Celsius. The thermal expansion coefficient for this product is approximately 4x10^-6/K at 25 degrees Celsius.Formule :C23H16ClN3O2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :401.84 g/molFood black 1

CAS :Alcian blue 8GX is a water-soluble dye that has been used for many years to stain the cell cytoplasm and other cellular structures. It binds to proteins, carbohydrates, lipids, and nucleic acids. Alcian blue 8GX is typically used as a histochemical staining agent in conjunction with phosphotungstic acid or hematoxylin. The binding of Alcian blue 8GX to cells is dependent on the presence of hydroxyl groups and it is transported by a passive process that is inhibited by lanthanum ions. This dye binds to glucosylceramide in the cerebellar purkinje neurons, which can be detected using electron microscopy. Alcian blue 8GX has been shown to enhance protein synthesis in human serum, but does not affect this process at low energy levels such as those found in diabetic patients.Formule :C56H68N16S4Cl4CuCouleur et forme :PowderMasse moléculaire :1,298.87 g/molBrilliant cresyl blue
CAS :Brilliant cresyl blue is a reactive dye that is used as a model system for mitochondrial membrane potential. It is injected into the oocyte and polymerase chain reaction (PCR) is performed to detect mitochondrial functions. The dye can be detected with optical sensors, which are sensitive to UV light. When the dye migrates from the mitochondria to the cytoplasm, it can be detected by UV-sensitive sensors. This process can help scientists determine if there are any defects in mitochondrial membrane potential.Formule :(C17H21N4O)2•ZnCl4Couleur et forme :Green PowderMasse moléculaire :400.97 g/mol4-Hydroxyphenethyl alcohol
