Quality Control

Our Glyoxylic Acid Ethyl Ester Diethyl Mercaptal is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed to exclude humidity.
