Quality Control

Our Isopropyl 4-Oxo-4-[(Tributylstannyl)Oxy]Butyrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis (Tin content), to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with customer specifications and internal quality standards. For custom synthesis or specific purity requirements, our technical team is available to discuss tailored QC protocols.

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 compound is easily oxidized and should be handled and stored under an inert atmosphere (e.g., nitrogen or argon) when possible. Keep away from strong acids and incompatible organic solvents. For long-term stability, consider storage at lower temperatures (2-8°C).
