Gadopentetate Dimeglumine

Gadopentetate Dimeglumine is the N-methylglucamine salt of the gadolinium complex of diethylenetriamine pentaacetic acid. It is an injectable contrast medium for magnetic resonance imaging. It is provided as a sterile, clear, and colorless to slightly yellow aqueous solution for intravenous injection. It is use with magnetic resonance imaging (MRI) in adults, and pediatric patients to visualize lesions with abnormal vascularity in the brain, spine and associated tissues as well as lesions with abnormal vascularity in the head and neck, to facilitate the visualization of lesions with abnormal vascularity in the body.

Gallic Acid

Gallic acid is a trihydroxybenzoic acid, a type of phenolic acid, a type of organic acid, found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. Gallic acid is found both free and as part of tannins. Salts and esters of gallic acid are termed 'gallates'. It is commonly used in the pharmaceutical industry. It is used as a standard for determining the phenol content of various analytes by the Folin-Ciocalteau assay; results are reported in gallic acid equivalents. Gallic acid can also be used as a starting material in the synthesis of the psychedelic alkaloid mescaline. Gallic acid seems to have anti-fungal and anti-viral properties. It acts as an antioxidant and helps to protect our cells against oxidative damage. Gallic acid is also used to treat albuminuria and diabetes. Some ointments to treat psoriasis and external haemorrhoids contain gallic acid.

In 1871, existence of gallium was first predicted by Russian chemist Dmitri Mendeleev, who named it "eka-aluminium" on the basis of its position in his periodic table. It was discovered spectroscopically by Paul Emile Lecoq de Boisbaudran in 1875 by its characteristic spectrum in an examination of a sphalerite sample. It is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures; this makes possible its use in high-temperature thermometers. In semiconductors, the major-use compound is gallium arsenide used in microwave circuitry and infrared applications. It is also used in alloys and fuel cells. Gallium is not known to be essential in biology, but because of the biological handling of gallium's primary ionic salt gallium(III) as though it were iron(III), the gallium ion localizes to and interacts with many processes in the body in which iron(III) is manipulated. As these processes include inflammation, which is a marker for many disease states, several gallium salts are used, or are in development, as both pharmaceuticals and radiopharmaceuticals in medicine.

Gallium Nitrate

Gallium nitrate is a drug that is used to treat hyper-calcemia, or too much calcium in the blood. This condition may occur when individuals develop various types of cancer. Gallium nitrate is also known by the common brand name Ganite.Gallium nitrate is believed to exert a hypocalcemic effect by inhibiting calcium resorption from bone. Gallium nitrate localizes preferentially where bone resorption and remodeling is occurring, and inhibits osteoclast activity. Inhibition of resorption may occur via a reduction in increased bone turnover.

Gallium Nitrate Industrial Grade 99%

Gallium nitrate is in hydrate compound normally, like nonahydrate, octahydrate and so on. They are both white crystal powder and tend to dissolve in water. Gallium metal, gallium hydroxide or gallium(III) oxide is the raw material for them. Gallium(III) nitrate hydrate turns into anhydrous compound by vacuum drying  and drying for 48 hour at 40℃.  Their storage should avoid reducing agent and oxidizable material. They melt at 65℃. It hydrolyzes once dissolving in water, which tend to dissolve in ethyl alcohol too.

Gallium Trichloride Industrial Grade 99%

Gallium trichloride  is colorless needle-like hygroscopicity crystal, which fume when contact with moist in air and hydrolyze. It reacts violently in air. GaCl3 is covalent minor metal salt, which is bipolymer when its gas is at about 270℃. It tend to dissolve in water and emit a lot of heat. GaCl3 also tend to dissolve in ether, benzene and other organic solvents, when dissolve in liquid ammonia, it forms ammonia complex. When temperature is less than the heating point, gallium(III) chloride tend to sublime in vacuum. Gallium metal or gallium(III) oxide is the raw material.
