Import Tips

Provide detailed chemical analysis (NMR, chiral purity >98%) and CAS number (875-74-1) to confirm identity and enantiomeric purity

Include end-use statement specifying pharmaceutical intermediate use to avoid misclassification as general chemical

Ensure proper Hazard Communication labeling (DOT UN 3261) and stabilizers if supplied in solution form
