  • Patent Blue A

    CAS :
    <p>Patent Blue A is a blue pigment with a deep color, which is used in detergent compositions. This pigment has a hydroxyl group on the surface and can be synthesized by reacting zirconium oxide with quinoline derivatives in an acidic solution. Patent Blue A has been shown to have good dispersibility and stability. It is insoluble in water but soluble in organic solvents such as chloroform and benzene. It also shows good radiation resistance and thermodynamic stability, making it suitable for use in medical devices or other products exposed to radiation, such as blood culture plates.</p>

  • Mercuric oxide red

    Produit contrôlé
    CAS :
    <p>Mercuric oxide red is a dinucleotide phosphate that has been used as an oxidation catalyst in organic synthesis. Mercuric oxide red is also used as a reagent for the conversion of glycoside derivatives to their corresponding mercuric salts. It can be used in the determination of certain metabolites, such as amino acids and fatty acids, in biological samples. In addition, it can be used to detect lipid peroxidation and oxidative stress. For example, Mercuric oxide red has been shown to have the ability to bind to Toll-like receptor 4 (TLR4). This binding induces the production of pro-inflammatory cytokines, including IL-6. Mercuric oxide red also inhibits plasma mass spectrometry by suppressing ionization and reducing fragmentation.</p>

  • Iron oxide black

    Produit contrôlé
    CAS :
    <p>Iron oxide black is a reactive dye that is used in wastewater treatment. It is an oxide of iron that can be synthesized from sodium carbonate and langmuir adsorption isotherm. Iron oxide black has been shown to have a colloidal gold-like color, chemical stability, and constant pressure. The particle size of this compound ranges from 10-1000 nm and it reacts with a solution containing anhydrous sodium carbonate to form magnetite nanoparticles. Iron oxide black also has an asymmetric synthesis reaction with ferric chloride and nitric acid, which produces magnetic nanoparticles.</p>

  • Silicon nitride - predominantly β-phase, -325 mesh

    CAS :
    <p>Silicon nitride is a compound of silicon and nitrogen. It is used in the preparation of high purity silicon, as well as in the production of semiconductors, electronic devices, and other products. Silicon nitride is also used to make parts for aircraft engines and turbines. The thermal expansion coefficient of silicon nitride is typically 5x10-6/°C, which makes it ideal for use in high-temperature environments. Silicon nitride has antimicrobial properties that may be due to its ability to release hydrogen fluoride and water vapor when heated. These compounds are toxic to bacteria and fungi, making silicon nitride a potential candidate for use in biomedical implants or medical devices such as catheters or prosthetic joints. Silicon nitride is chemically stable at temperatures up to 1000°C, making it an excellent material for high-temperature applications such as aerospace engine components. Silicon nitride can also be used as a sample preparation tool because it can remove impurities from samples without</p>
