In chemistry, a reaction intermediate, or intermediate, is a molecular entity arising within the sequence of a stepwise chemical reaction. It is formed as the reaction product of an …

: a chemical compound synthesized from simpler compounds and usually intended to be used in later syntheses of more complex products. : a usually short-lived chemical species formed in a …

We call the carbocation, which exists only transiently during the course of the multistep reaction, a reaction intermediate. As soon as the intermediate is formed in the first step by reaction of …

Most synthetic processes involve transformation of some readily available and often inexpensive substance to some desired product through a succession of steps. All the substances …

Intermediate reactions are common in the biological world; a prime example can be seen in the metabolism of metabolites and nutrients. The lifetime of an intermediate is usually short …

Jul 10, 2019 · Intermediates tend to be extremely reactive and short-lived, so they represent a low concentration in a chemical reaction compared with the amount of reactants or products. Many …

INTERMEDIATE definition: 1. being between two other related things, levels, or points: 2. being between two other related…. Learn more.

Oct 7, 2025 · In chemistry, a reaction intermediate or an intermediate is a molecular entity that is formed from the reactants (or preceding intermediates) and reacts further to give the directly …

Oct 22, 2025 · This thorough reference will help you chemical intermediates, from nitrogen-based nitrenes to the fundamental question of how many types of intermediates are there.

Intermediates are distinct, short-lived chemical species with defined structural features - they may have partially broken or newly forming bonds but retain a stable enough configuration to be …
