Quality Control

Our 4'-Hydroxy-2-Methylpropiophenone is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets precise customer requirements. Certificates of Analysis (COA) with full traceability are provided with every shipment.

Storage

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