Quality Control

Every batch of our Benzoic Acid, 4-[[11-[(1-Oxo-2-Propen-1-Yl)Oxy]Undecyl]Oxy]-, 1,1'-(1,4-Phenylene) Ester is produced and tested under a strict Quality Management System. We ensure compliance with critical parameters for advanced material applications, including purity, reactivity, and absence of polymerization inhibitors unless specified. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical specifications is provided with each shipment to guarantee batch-to-batch consistency and performance reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive. To maintain reactivity and prevent premature polymerization or hydrolysis, keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Isolate from heat, sparks, and open flame.
