Quality Control

Our production of (R)-4-Hydroxy-5-methyl-5-hexen-2-one adheres to stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity (typically by HPLC), chiral purity, and impurity profiles. We are committed to meeting the exacting standards required for research and cGMP manufacturing applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and degradation. Keep away from heat and incompatible materials.
