Overview
Trityl candesartan cilexetil (CAS 170791-09-0) is a key pharmaceutical intermediate used in the synthesis of the antihypertensive drug candesartan. Its molecular formula is C42H38N6O4. The core process involves coupling 5-hydroxymethylbenzimidazole with trityl-protected precursors under strict anhydrous conditions to ensure high purity.
Application
- Pharmaceutical Manufacturing: Serves as the essential starting material for large-scale production of candesartan cilexetil tablets.
- R&D Laboratories: Utilized in stability studies and formulation development for new angiotensin II receptor blockers.
- Quality Control: Applied as a reference standard in HPLC analysis for active pharmaceutical ingredient verification.
Precautions
- Storage: Keep in tightly sealed containers at 2-8°C, protected from light and moisture.
- Safety: Handle with appropriate PPE; avoid inhalation or skin contact due to potential irritant properties.
- Regulatory: Intended solely for industrial manufacturing; not approved for direct clinical use without further processing.
