Quality Control

Our production of 1,7-Bis(4-Hydroxyphenyl)Hepta-1,4,6-Trien-3-One adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical specifications. We support custom synthesis and can tailor purity grades to meet specific research or industrial project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized (store under inert atmosphere), prolonged exposure to air, light, or elevated temperatures should be avoided. For long-term storage, consider packaging under an inert gas such as nitrogen or argon.
