| Targets |
3-Bromo-2-chloropyridine is used as a reactant in the preparation of dihydrobenzofuran amides as γ-secretase modulators. These modulators lower Aβ42 in the brain and avoid P-glycoprotein mediated efflux. The compound can be used for the synthesis of 5-hydroxytryptamine (5-HT) and serotonin, neurotransmitters that regulate mood. The compound's primary targets are related to γ-secretase modulation and neurotransmitter synthesis. The compound acts as a nucleophile in chemical reactions.
