62613-15-4 Usage
General Description
Diphenyliodonium hexafluoroarsenate is a chemical compound that contains the cation diphenyliodonium and the anion hexafluoroarsenate. It is a white crystalline solid that is insoluble in water and soluble in organic solvents. This chemical is commonly used as a source of hexafluoroarsenate in organic synthesis and as a light-sensitive reagent in the production of photoresists for microelectronic devices. It is also used as a photoinitiator for cationic polymerization and as a catalyst in various chemical reactions. Diphenyliodonium hexafluoroarsenate is considered to be a stable and relatively non-toxic compound when handled and used in accordance with proper safety procedures.
Check Digit Verification of cas no
The CAS Registry Mumber 62613-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,1 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 62613-15:
(7*6)+(6*2)+(5*6)+(4*1)+(3*3)+(2*1)+(1*5)=104
104 % 10 = 4
So 62613-15-4 is a valid CAS Registry Number.

Method for making diaryliodonium polyhalometalloid salts
-
, (2008/06/13)
A method is provided for making certain diaryliodonium salt photoinitiators, based on the initial formation of diaryliodonium perchlorate which is formed from a diaryliodonium bisulfate precursor. The diaryliodonium perchlorate is then reacted with a counter ion source, such as an alkali metal hexafluoro metalloid salt, to produce the desired diaryliodonium salt, which can be used as a photoinitiator. The iodonium salt photoinitiators made by the method of the present invention can be used to effect the cure of a variety of cationically polymerizable organic materials, such as epoxy resins.
