Nitric Acid

Nitric acid is commonly used as a strong oxidizing agent. The main use of nitric acid is for the production of fertilizers. Other important uses include etching and dissolution of metals, especially as a component of aqua regia for the purification and extraction of gold, and in chemical synthesis. It has been used in various forms as the oxidizer in liquid-fueled rockets.

Nitrobenzene is an organic compound. It is produced on a large scale as a precursor to aniline. Although occasionally used as a flavoring or perfume additive, nitrobenzene is highly toxic in large quantities. In the laboratory, it is occasionally used as a solvent, especially for electrophilic reagents. It is also used in shoe and floor polishes, leather dressings, paint solvents, and other materials to mask unpleasant odors. A significant merchant market for nitrobenzene is its use in the production of the analgesic paracetamol. It is also used in Kerr cells, as it has an unusually large Kerr constant.

Oleic Acid

Oleic acid in chemical terms is monounsaturated omega-9 fatty acid because of the single double bond between the carbons. It has the formula of C18H34O2 and is pale yellow or brownish yellow oily liquid with lard-like odor. Oleic acid is the emollient in cosmetics, an emulsifying agent in soaps, the excipient in pharmaceuticals and solubilizer in aerosol products.

Properties Suppliers

Orcinol is a natural phenolic organic compound that occurs in many species of lichens including Rocella tinctoria and Lecanora. It can be formed by fusing extract of aloes with potash. It is used in the production of the dye orcein and as a reagent in some chemical tests for pentoses, such as Bial's Test.

Organic Germanium Industrial Grade 99%

Organic germanium includes synthetic organic germanium, natural organic GE and biological organic Ge. The synthetic one is carboxyethyl germanium sesquioxide that is Ge-132, spirogermanium, Furan germanium derivates and other antiviral, anti-inflammatory and anticancer organic Ge. It is compound that has wide pharmacologic action, but if over dose, it cause acalcerosis. Natural organic Ge is extracted from natural plants, which gets no toxic and side effect to human body. Biological organic Ge is planting germanium compounds into biological body, for example yeast, germ, macro fungi, vegetable and so on.  Ge-132 is short of (GeCH2CH3COOH)2O3

Organic Germanium

Ge-132 applies to functional health food, medicine, cosmetics and so on.
