7790-78-5 Usage
Uses
Used in Chemical Analysis:
Cadmium chloride hydrate is used as a standard solution in chemical analysis for the calibration of instruments and the preparation of reference materials.
Used in Photocopying Industry:
In the photocopying industry, cadmium chloride hydrate is used as a component in the production of toner, which is essential for the reproduction of images and text on paper.
Used in Dyeing Industry:
Cadmium chloride hydrate is used as a mordant in the dyeing industry, particularly for natural fibers such as cotton, wool, and silk. It helps to fix dyes onto the fibers, improving colorfastness and resistance to fading.
Used in Electroplating Industry:
In the electroplating industry, cadmium chloride hydrate is used as a source of cadmium ions for the deposition of cadmium coatings on various metal surfaces. These coatings provide corrosion resistance, wear resistance, and improved electrical conductivity.
Used in Pyrotechnic Devices:
Cadmium chloride hydrate is used in pyrotechnic devices, such as flares and fireworks, due to its ability to produce a bright yellow color when burned. This property makes it a valuable component in creating visually striking pyrotechnic effects.
Safety Profile
Confirmed human
carcinogen. Poison by ingestion and
intraperitoneal routes. Experimental
reproductive effects. Human mutation data
reported. When heated to decomposition it
emits toxic fumes of Cland Cd. See also
CADMIUM CHLORIDE, CADMIUM
COMPOUNDS, and CHLORIDES.
Waste Disposal
Cadmium chloride hydrate is preferred to convert the salt to the nitrate, precipitate it with H2S, filter, wash and dry the precipitate and return it to the supplier.
Check Digit Verification of cas no
The CAS Registry Mumber 7790-78-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7790-78:
(6*7)+(5*7)+(4*9)+(3*0)+(2*7)+(1*8)=135
135 % 10 = 5
So 7790-78-5 is a valid CAS Registry Number.
