109613-93-6 Usage

Uses

Used in Pharmaceutical Industry:
Pyridine,3,4-dimethoxy-(9CI) is used as a key intermediate in the total synthesis of endothelin-converting enzyme (ECE) antagonists. These antagonists are important in the development of drugs for the treatment of various cardiovascular and cerebrovascular diseases, as they help regulate the activity of endothelin, a potent vasoconstrictor peptide.
In the synthesis process, 3,4-Dimethoxypyridine serves as a building block for the formation of more complex molecules with potential therapeutic effects. Its unique structure and reactivity make it a valuable component in the design and development of novel ECE antagonists, which can be tailored to target specific disease conditions and improve patient outcomes.

Check Digit Verification of cas no

The CAS Registry Mumber 109613-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,1 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109613-93:
(8*1)+(7*0)+(6*9)+(5*6)+(4*1)+(3*3)+(2*9)+(1*3)=126
126 % 10 = 6
So 109613-93-6 is a valid CAS Registry Number.

A concise approach towards the synthesis of WS75624 a and WS75624 B via the cross-metathesis of vinyl-functionalized thiazoles

Dash, Jyotirmayee,Melillo, Bruno,Arseniyadis, Stellios,Cossy, Janine

, p. 2246 - 2249 (2011/05/05)

Synthetic approach towards precursors of WS75624 A and WS75624 B, two potent endothelin converting enzyme (ECE) inhibitors and potential antihypertensive agents, is reported featuring a key cross-metathesis between a vinyl-functionalized thiazole and a terminal olefin. As the two natural products only differ by the nature of their hydroxyalkyl side-chain, our convergent strategy enable the synthesis of key intermediates of both molecules in a limited amount of steps.
