Quality Control

Our (5E,9E,13E,17E,21E,25E,29E)-6,10,14,18,22,26,30,34-Octamethyl-5,9,13,17,21,25,29,33-Pentatriacontaocten-2-One is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and structural integrity. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support custom synthesis and can tailor purity grades to meet specific R&D or cGMP starting material requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is easily oxidized; prolonged exposure to air should be avoided. Keep away from heat, sparks, and open flame.
