Quality Control

Our (+)-2-Methyl-2-(4-Methyl-3-Pentenyl)-7-Propyl-2H-1-Benzopyran-5-Ol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis (HPLC, optical rotation), identity confirmation (IR, NMR), and impurity profiling to ensure it meets exacting R&D and production standards. Certificates of Analysis (COA) with detailed specifications are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
