- The product range (0.860-0.880 / 1.464-1.474) is a perfumery/industrial-grade window; we tighten to the standard intervals (0.875-0.883 / 1.464-1.470) on request for food/pharma grades
- Optical rotation and UV/CD value are measured on every batch and reported on the COA
- GB/T 45139-2024 (identical to ISO 7358:2021) is used for the HPLC determination of 5-MOP content
- Full property set is verified by in-house QC before each shipment
