Applications of 157911-56-3
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Intermediate for antidiabetic drugs | Serves as a key alkylating agent in the synthesis of tricyclic or side-chain structural motifs of dipeptidyl peptidase-4 (DPP-4) inhibitors, such as sitagliptin. |
| Pharmaceutical Industry | Building block for drug molecules | Introduces the 2,4,5-trifluorobenzyl functional group into target molecules via the high reactivity of benzyl bromide, enabling construction of fluorinated aromatic drug scaffolds with tailored pharmacokinetic properties. |
| Organic Synthesis | Preparation of fluorinated aryl derivatives | Introduces the 2,4,5-trifluorobenzyl group into substrates such as alcohols, amines, or thiols via nucleophilic substitution, for the synthesis of fine chemicals or subsequent complex functional molecules. |
