Gold Hydroxide Industrial Grade 99%

Gold hydroxide is a brown precious metal compound, which tend to decompose when heating. It is insoluble in water and dilute acid, however soluble in strong acid, strong alkali and sodium cyanide solution. Gold(III) hydroxide is amphoteric,which is not stable and tend to decompose to AuO(OH) when heating to 100℃, Au2O3 when heating to 140-150℃. Potassium chloroaurate or gold chloride is the raw material.

Guaiacol

Guaiacol is a naturally occurring organic compound. Although it is biosynthesized by a variety of organisms, this colorless aromatic oil is usually derived from guaiacum or wood creosote. It is present in wood smoke, resulting from the pyrolysis of lignin. Guaiacol is a precursor to various flavorants such as eugenol and vanillin. Its derivatives are used medicinally as an expectorant, antiseptic, and local anesthetic. It also can be used as a dye in chemical reactions as oxygen will turn guaiacol from colorless to brown.

Guanine

Guanine is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine. In DNA, guanine is paired with cytosine. It is a derivative of purine, consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds. Being unsaturated, the bicyclic molecule is planar. The guanine nucleoside is called guanosine. In the cosmetics industry, crystalline guanine is used as an additive to various products, where it provides a pearly iridescent effect. It is also used in metallic paints and simulated pearls and plastics. It provides shimmering luster to eye shadow and nail polish.
