Quality Control

Our production of Phosphonium, (2-tert-Butoxy-2-Hydroxyvinyl)Triphenyl-, Hydroxide, Inner Salt, (E)- adheres to stringent quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot is characterized by advanced analytical techniques including NMR, HPLC, and FT-IR to confirm identity, isomeric purity ((E)-isomer), and chemical integrity. We provide comprehensive Certificates of Analysis (COA) with all shipments, detailing purity, assay, and impurity profiles to support your quality management systems.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after initial opening to prevent decomposition. Keep away from heat and incompatible materials.
