Applications & Uses

Uses

A piperazine derivative and a selective antagonist at D3 receptors that influences the expression of cocaine-induced conditioned place preference (CPP).

Uses

It is used as pharmaceutical intermediate. N-alkylated 1-(2-methyoxyphenyl)piperazines markedly improved affinity and selectivity of the dopamine D3 receptor which is recognized as a potential therapeutic target for the treatment of various neurological and psychiatric disorders.

Uses

1-(2-Methoxyphenyl)piperazine can be used:To functionalize pyrazolylvinyl ketones via Aza-Michael addition reaction.To prepare cyclic amine substituted Trger′s base derivatives.To prepare functionalized bis(mercaptoimidazolyl)borates by reacting with the activated ester, [(1-methyl-2-mercaptoimidazol-5-yl)carbonyl]succinimide.
