General Description
4-Hydroxyphenyldimethylsulfonium methyl sulfate is a chemical compound that consists of a sulfonium cation with a hydroxyphenyl group and two methyl groups attached to it, and a methyl sulfate anion. It is commonly used as a photosensitizer in the photoresist industry, as it is able to initiate polymerization upon exposure to light. 4-HYDROXYPHENYLDIMETHYLSULFONIUM METHYL SULFATE is also utilized in the production of photoacid generators for photoresist formulations used in the semiconductor industry. Additionally, it can act as a reactive intermediate in organic synthesis, and has been studied for its potential use in photodynamic therapy for cancer treatment. Due to its photosensitive properties and potential applications in various industries, 4-hydroxyphenyldimethylsulfonium methyl sulfate is a valuable and versatile chemical compound.
Check Digit Verification of cas no
The CAS Registry Mumber 32279-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,2,7 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 32279-04:
(7*3)+(6*2)+(5*2)+(4*7)+(3*9)+(2*0)+(1*4)=102
102 % 10 = 2
So 32279-04-2 is a valid CAS Registry Number.
