6443-90-9 Usage
General Description
Pyridine iodine monochloride complex, also known as iodine monochloride pyridine complex, is a chemical compound formed by the reaction of pyridine with iodine monochloride. It is a yellowish crystalline solid that is usually synthesized by reacting pyridine with iodine monochloride in a chlorinated solvent. The complex is commonly used as a mild electrophilic iodinating agent in organic synthesis, particularly in the iodination of aromatic compounds. It exhibits good regioselectivity and is known for its ability to efficiently iodinate electron-rich aromatic systems. The complex also finds applications in the synthesis of various iodinated organic compounds and in the preparation of diverse organic intermediates. Additionally, it is used as a reagent for the oxidation of organic compounds and is a valuable tool in the field of synthetic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 6443-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,4 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6443-90:
(6*6)+(5*4)+(4*4)+(3*3)+(2*9)+(1*0)=99
99 % 10 = 9
So 6443-90-9 is a valid CAS Registry Number.

Pyridinium lodochloride: An efficient reagent for lodination of hydroxylated aromatic ketones and aldehydes
Khansole, Sandeep V.,Mokle, Shyam S.,Sayyed, Mudassar A.,Vibhute, Yeshwant B.
experimental part, p. 871 - 874 (2009/12/01)
Direct iodination of several reactive aromatic compounds like hydroxy substituted acetophenones and aldehydes with pyridinium iodochloride (PyICl) proceeded smoothly to afford the corresponding aromatic iodides in good to excellent yield. Pyridinium iodochloride has been found to be an efficient solid iodinating reagent with no hazardous effect and it can be handled safely.
