Description
BENZIODARONE is a pharmaceutical compound that serves as a uricosuric drug, which means it promotes the excretion of uric acid in the urine. This property makes it a valuable treatment option for managing hyperuricemia, a condition characterized by elevated levels of uric acid in the blood.
Uses
Used in Pharmaceutical Industry:
BENZIODARONE is used as a uricosuric agent for controlling hyperuricemia, particularly in patients who have undergone renal transplantation. By increasing the excretion of uric acid, BENZIODARONE helps to maintain healthy uric acid levels and prevent complications associated with hyperuricemia, such as gout and kidney stones.

Manufacturing Process
The starting product 2-ethyl-3-benzofuranyl p-hydroxyphenyl ketone
(benzaron) was prepared in 4 steps:
1. First step was a reaction of salicylic aldehyde with chloroacetone to produce
2-acetyl-1-benzofuran.
2. It was reduced by hydrazine hydrate in an alkaline medium by process of
Hyuang-Minlon, J.A.C.S., 1946, 68, 2487 to give 2-ethyl-1-benzofurane.
3. 2-Ethyl-3-(4-methoxybenzoyl)-1-benzofuran was obtained from 2-ethyl-1-
benzofuran and 4-methoxy-benzoylchloride in a presence of tin tetrachloride.
4. It was heated with pyridine hydrochloride at 200°-220°C to give 2-ethyl-3-
benzofuranyl p-hydroxyphenyl ketone (benzaron) as described in N.P.B.Hoi,
C.Beaudet; US Patent No. 3,012,042; Dec. 5, 1961.
Benzaron (1 part) was dissolved in a very slight excess of 3% caustic soda. To
this solution is gradually added a slight excess of iodine dissolved in a 25%
aqueous solution of potassium iodide. The resultant solution is acidified with a
20% solution of sodium bisulphite, centrifuged, washed with water and then
recrystallized in acetic acid to give of 2-ethyl-3-benzofuranyl 4-hydroxy-3,5-
diiodophenyl ketone. MP: 167°C.

Check Digit Verification of cas no
The CAS Registry Mumber 68-90-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68-90:
(4*6)+(3*8)+(2*9)+(1*0)=66
66 % 10 = 6
So 68-90-6 is a valid CAS Registry Number.
