4-Fluoroephedrine, also known as 4-fluoro-β-hydroxy-N-methylamphetamine, is a substituted phenethylamine, amphetamine, and β-hydroxyamphetamine derivative. [6] [1] It is the 4-fluoro analogue of ephedrine. [6] [1] The synthesis of 4-fluoroephedrine has been described. [7] It can serve as a precursor in the synthesis of 4-fluoromethamphetamine ...
This synthesis was a by-product of a search for ephedrine, a bronchodilator used to treat asthma extracted exclusively from natural sources. Over-the-counter use of substituted amphetamines was initiated in the early 1930s by the pharmaceutical company Smith, Kline & French (now part of GlaxoSmithKline ), as a medicine ( Benzedrine ) for colds ...

Ephedrine promotes modest short-term weight loss, [24] specifically fat loss, but its long-term effects are unknown. [25] In mice, ephedrine is known to stimulate thermogenesis in the brown adipose tissue, but because adult humans have only small amounts of brown fat, thermogenesis is assumed to take place mostly in the skeletal muscle.
Substituted phenethylamines (or simply phenethylamines) are a chemical class of organic compounds that are based upon the phenethylamine structure; [note 1] the class is composed of all the derivative compounds of phenethylamine which can be formed by replacing, or substituting, one or more hydrogen atoms in the phenethylamine core structure with substituents.

A wide variety of alkaloid and non-alkaloid compounds have been identified in various species of Ephedra.Of the six ephedrine-type ingredients found in ephedra (at concentrations of 0.02-3.4%), the most common are ephedrine and pseudoephedrine, [13] which are the sources of its stimulant and thermogenic effects.
