Every production lot is independently verified to exceed 99% purity through reversed-phase HPLC with UV detection at 214 nm or 220 nm. The reported purity percentage reflects the target peak area relative to all detected peaks. Full analytical data, including the chromatogram, is published directly on each product page before you order.
