Quality Control

This analytical standard is produced under strict quality-controlled conditions to ensure accuracy and traceability. Each batch is analyzed to confirm identity, purity, and concentration against certified reference standards. A comprehensive Certificate of Analysis (COA) is provided, detailing the results of tests including assay, solvent composition verification, and stability assessment. Our quality system is designed to support compliance with GMP/GLP principles for laboratory use.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C). Due to the highly volatile nature of the acetone solvent, ensure containers are securely sealed when not in use to prevent evaporation and concentration change. Keep away from heat, sparks, and open flame.
