Could you please give me an idea of the optical purity of this product? The optical rotation value stated of -50.2 corresponds to 100% enantiopure alpha-pinene so I just want to check that this value listed is what has been tested rather than literature

Asked by: Joshtibbetts
The enantiomeric excess is measured as the optical purity and is lot-specific and stated on the CoA. The Optical Activity listed in the Technical Information on our website is a reference only. Please contact our Technical Service Department to request a CoA for a current or recent lot.
