Quality Control

We maintain stringent quality control protocols for our fine chemical products. Each batch of 2H-Naphtho[1,2-B]Pyran-6-Ol, 2,5-Dimethyl-2-[(3E,7E)-4,8,12-Trimethyl-3,7,11-Tridecatrienyl]- (9Ci) undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay purity (by HPLC), related substances, and physical characteristics are provided and available upon request. Our quality system is designed to support research and development needs with reliable, high-purity materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Recommended storage temperature is between 2°C and 8°C for long-term stability, although short-term storage at controlled room temperature (15-25°C) may be acceptable. Keep away from heat, sparks, and open flame. Due to the unsaturated nature of the molecule, storage under an inert atmosphere (e.g., nitrogen or argon) is advised for optimal shelf life.
