Quality Control

Our Ik 29 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, NMR for structural confirmation, and KF titration for moisture content. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment. We support compliance with REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed in a dry environment to prevent absorption of atmospheric moisture. Keep away from strong acids and strong bases.
