Purpose (USE)
Purpose Methyl 2-(2-chloro-1-ethylene)hydrazidecarboxylate is a very important intermediate in the synthesis of aprepitant. Aprepitant (English name aprepitant) is the first neurokinin 1 (NK-1) receptor blocker approved by the US FDA in 2003. It works by interacting with NK-1 receptors (mainly found in the central nervous system). system and its periphery) combine to block the effects of substance P.
