Quality Control

Our Isopropylsulfinic acid, sodium salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, purity profiling, and identification, to ensure it meets high-purity standards suitable for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to prevent oxidation and moisture uptake. Keep away from strong oxidizing agents.
