Quality Control

Our Ethyl 2-(4-Chlorophenylsulfinyl)Acetate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting critical parameters such as assay, chiral purity (enantiomeric excess), and impurity profiles. Our quality commitment ensures the material meets the stringent requirements for use in regulated GMP intermediates and advanced research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in darkness. For long-term storage, consider an inert atmosphere to maintain optimal stability.
