Quality Control

Our 4-Heptylphenyl 4-(trans-4-Propylcyclohexyl)Benzoate is produced under strict quality management systems to ensure batch-to-batch consistency and high purity, critical for liquid crystal applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, isomeric composition, and impurity profiles. We support customer audits and can provide material to meet specific ISO or internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C/59-77°F). This material is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve stability and prevent degradation.
