25297-77-2 Usage
General Description
1,2-dimethyl-7-phenyl-1,2,3,4-tetrahydroisoquinolinium iodide, also known as MIH (methoisoquinolinium iodide), is a chemical compound that is commonly used as a phase transfer catalyst in organic synthesis. It is a quaternary ammonium salt and is typically used to facilitate the transfer of a reactant from one phase to another, such as from an organic phase to an aqueous phase. MIH has a bulky and aromatic structure due to the presence of a phenyl group and methyl groups, which allows it to efficiently catalyze reactions involving bulky substrates. It is soluble in various organic solvents and is often used in reactions such as quaternary ammonium hydroxide catalyzed alkylation, the Hofmann elimination reaction, and other quaternary ammonium salt-catalyzed reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 25297-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,9 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25297-77:
(7*2)+(6*5)+(5*2)+(4*9)+(3*7)+(2*7)+(1*7)=132
132 % 10 = 2
So 25297-77-2 is a valid CAS Registry Number.
