Quality Control

Our Isooctyl 2-Mercaptoethyl Phthalate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. Specifications are designed to meet the demanding requirements of industrial and R&D applications. A comprehensive Certificate of Analysis (COA), detailing assay, identity, and impurity profiles, is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to the presence of the mercapto group, prolonged exposure to air should be minimized to prevent potential oxidation.
