Quality Control

Every batch of our 3-Meso2-4-Me-2',3',4',5,5'-Pentacb reference standard is manufactured and verified under strict quality management protocols. The solution is prepared gravimetrically using high-purity materials and analyzed to confirm concentration accuracy and solvent purity. Certificates of Analysis (COA) are provided with each shipment, detailing the results of critical tests including assay, solvent verification, and stability indicators. Our quality system is designed to support GLP/GMP-compliant laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated). Due to the highly volatile nature of the nonane solvent, ensure containers are securely sealed when not in use and stored in a well-ventilated area. For long-term stability, it is recommended to store the vial in its original packaging.
