Candesartan Cilexetil Impurity 20(CAS: 170791-09-0)

Candesartan Cilexetil Impurity 20, also known as Candesartan Cilexetil Impurity 20 (CAS: 170791-09-0), is a white to off-white crystalline solid with a molecular weight of approximately 511.6 g/mol. It is slightly soluble in water and ethanol. The compound is stable under normal storage conditions but reacts with strong acids and bases. It is commonly used as an impurity in pharmaceutical applications.

Candesartan Cilexetil Impurity 20 (CAS: 170791-09-0) is typically synthesized through a series of chemical reactions involving the cilexetil esterification of candesartan. The process involves the use of organic solvents and catalysts to achieve high yield and selectivity. Laboratory scale synthesis often requires precise control of reaction conditions to ensure product purity.

Candesartan Cilexetil Impurity 20 (CAS: 170791-09-0) is primarily used in the pharmaceutical industry as a quality control impurity in candesartan-based medications. It is also relevant in research and development for the evaluation of impurities in drug formulations.

When handling Candesartan Cilexetil Impurity 20 (CAS: 170791-09-0), it is important to wear appropriate personal protective equipment (PPE) including gloves, safety glasses, and a lab coat. Work in a well-ventilated area or fume hood to avoid inhalation or skin contact. Ensure proper storage and disposal according to the safety data sheet (SDS). In case of spill, clean up using appropriate methods and seek assistance as necessary.
