Quality Control

Every batch of (S)-(4-Cyanophenyl) 4-Pentylthiobenzoate is manufactured under strict quality management systems and undergoes comprehensive analytical testing. We guarantee high enantiomeric purity and chemical identity to meet the stringent requirements of advanced material synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming specifications for assay, chiral purity, and related substances via validated methods such as HPLC and chiral chromatography.

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). Keep away from heat, open flames, and incompatible materials. Due to its light-sensitive nature, handling and packaging should minimize exposure to direct light.
