Quality Control

Our production of (+)-(1R)-4-Methyl-Cyclohex-3-Enecarboxylic Acid adheres to stringent quality protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed using advanced techniques including HPLC, chiral GC, and NMR to confirm identity, enantiomeric excess (ee), and purity. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
