Import Tips
• Provide polarimetry data showing [α]D +41° to +43° confirming natural D-isomer vs synthetic racemic mixtures
• GC-chiral analysis required to distinguish natural enantiomer from synthetic; include in CoA
• Store under nitrogen to prevent oxidation; declare inert atmosphere packaging on commercial invoice
