Product overview
A dichloropyridine with chlorine at C-3 and C-4 and ring hydrogens at C-2, C-5 and C-6. The 4-chlorine opposite the ring nitrogen is the position more exposed to nucleophilic aromatic substitution, whereas the 3-chlorine is the more typical site for metal-catalysed coupling, so the two chlorines can be addressed separately. The compound is used as an intermediate in organic synthesis and is a plausible dichloropyridine fragment for pharmaceutical and agrochemical analogues.
Application areas
Depending on the synthesis route and project requirements, this product may also be suitable for other related organic synthesis applications.
Potential uses
- The aryl-chlorine bond may be targeted in suitable catalytic cross-coupling or substitution chemistry, subject to ring activation and reaction conditions.
