Description
Valsartan, also known as ent-Valsartan, is the (R)-enantiomer of Valsartan (V095750). It is a white to off-white solid with specific chemical properties that make it useful in various applications.
Uses
Used in Pharmaceutical Industry:
Valsartan is used as an active pharmaceutical ingredient for the treatment of hypertension (high blood pressure). It functions as an angiotensin II receptor blocker, which helps in relaxing blood vessels and reducing blood pressure.
Used in Cardiovascular Applications:
In the field of cardiology, valsartan is utilized as a therapeutic agent for the management of heart failure and post-myocardial infarction (heart attack). Its ability to block angiotensin II receptors aids in improving heart function and reducing the risk of further cardiovascular events.
Used in Research and Development:
Valsartan is also used as a research compound in the development of new drugs and therapies related to hypertension and cardiovascular diseases. Its chemical properties and mechanism of action provide valuable insights for scientists working on novel treatments for these conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 137862-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,6 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137862-87:
(8*1)+(7*3)+(6*7)+(5*8)+(4*6)+(3*2)+(2*8)+(1*7)=164
164 % 10 = 4
So 137862-87-4 is a valid CAS Registry Number.

Synthesis of 5-Substituted 1 H-Tetrazoles from Nitriles by Continuous Flow: Application to the Synthesis of Valsartan

An efficient continuous flow process for the synthesis of 5-substituted 1H-tetrazoles is described. The process involves the reaction between a polymer-supported triorganotin azide and organic nitriles. The polymer-supported organotin azide, which is in situ generated with a polystyrene-supported triorganotin alkoxide and trimethylsilylazide, is immobilized in a packed bed reactor. This approach is simple, fast (it takes from 7.5 to 15 min), and guarantees a low concentration of tin residues in the products (5 ppm). The process was developed to aryl-, heteroaryl-, and also alkylnitriles and was applied for the synthesis of valsartan, an angiotensin II receptor antagonist.
