Description

Ephedrine Hydrochloride EP Impurity A is a product of the biotransformations of pseudoephedrine. It has been shown that this impurity can be formed in enzymatic reactions where pseudoephedrine is acted upon by β-unsaturated ketones or by filamentous fungi. Ephedrine Hydrochloride EP Impurity A is a chiral compound, which means that it has two different forms that are non-superimposable mirror images of each other. The enantiomers (left and right) are the individual molecules that make up the racemic mixture. In some cases, ephedrine hydrochloride ep impurity a may be present as a result of a reaction between pseudoephedrine and an enzyme preparation containing β-unsaturated ketones, such as acetone peroxide or benzoyl peroxide. This impurity has been shown to inhibit candida glabrata and to have kinetic properties similar to that of ephed
