Description
GOLD(I) IODIDE, also known as gold(I) iodide or chemically represented as AuI, is a compound consisting of gold and iodine in the +1 oxidation state. It is a yellowish to greenish-yellow powder that decomposes slowly at room temperature and rapidly at elevated temperatures. GOLD(I) IODIDE can be synthesized by adding potassium iodide (KI) to an acidic solution of chloroauric acid (HAuCl4).
Uses

GOLD(I) IODIDE is used as a chemical intermediate for the synthesis of various chemicals. Its unique properties and reactivity make it a valuable component in the production of different compounds.
Used in Pharmaceutical Industry:
GOLD(I) IODIDE is used as a precursor in the development of pharmaceutical compounds, particularly in the creation of gold-based drugs for the treatment of various medical conditions.
Used in Material Science:
In the field of material science, GOLD(I) IODIDE is utilized in the synthesis of novel materials with unique properties, such as conductivity or magnetism, which can be applied in various technological applications.
Used in Analytical Chemistry:
GOLD(I) IODIDE is employed as a reagent in analytical chemistry for the detection and quantification of specific elements or compounds due to its distinctive chemical properties and reactivity.
Purification Methods
It has been prepared by heating gold and iodine in a tube at 120o for 4 months. Since it decomposes to Au and I2 in the presence of UV light and heat, then the main impurity is Au. The salt is therefore purified by heating at 120o with I2 for several weeks. The crystals should be kept dry and in a cool place in the dark. [Weiss & Weiss Z Naturforsch 11B 604 1956.]
Check Digit Verification of cas no
The CAS Registry Mumber 10294-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,9 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10294-31:
(7*1)+(6*0)+(5*2)+(4*9)+(3*4)+(2*3)+(1*1)=72
72 % 10 = 2
So 10294-31-2 is a valid CAS Registry Number.

Gold(I) halides have been obtained from Au2Cl6: a) with cyclohexene as halogen acceptor (AuCl); b) by halide exchange with i-Pr-Br, followed by treatment with cyclohexene at low temperature (AuBr); c) by halide exchange with i-Pr-I at room temperature (AuI).Carbonylation of AuBr in dichloromethane or treatment of Au2Br6 with CO and cyclohexene in 1,2-dibromoethane yielded AuBr(CO), characterized by IR and 13C NMR spectra in solution, the latter at low temperature
