Chemical structure

Isomerism

Epinephrine acid tartrate exhibits chiral isomerism, primarily due to the presence of a stereocentre at the beta-carbon of the side chain attached to the catechol ring. This chiral centre allows for the existence of two enantiomers: (R)-epinephrine and (S)-epinephrine. The biologically active form is the (R)-enantiomer, also known as (-)-epinephrine, which is naturally produced by the adrenal glands. The tartrate component, derived from tartaric acid, is itself chiral and typically used in its L-form, forming a salt that enhances the compound’s solubility and stability.

Commercial production

The production of epinephrine acid tartrate begins with the synthesis of pure (-)-epinephrine, which is typically achieved through either resolution of racemic epinephrine or asymmetric synthesis using chiral catalysts to ensure high enantiomeric purity. Once the active base is obtained, it is reacted with L-(+)-tartaric acid in a controlled aqueous or ethanolic solution to form the acid tartrate salt.

Impact on climate of production and use

Published GHG data is not available for most pharmaceuticals. However, according to industry, global averages suggest producing 1 kg of a typical active pharmaceutical ingredient can range from 10 to 100 kg CO₂e for small molecule drugs and potentially up to 1000 kg CO₂e for complex biologicals such as vaccines, depending on the drug type, its formulation, complexity of synthesis, solvent recovery, and energy sources used.
