Quality Control

Our Pentyl 3-Methyl-2-Butenoate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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 appropriate for long-term storage or after opening to maintain purity and prevent degradation.
