Quality Control

Our 4'-[(S)-2-Methylbutyl]Biphenyl-4-Carbonitrile is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure it meets the high standards required for electronic and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity (typically >98.5% by HPLC), enantiomeric excess (e.e.), and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
