Quality Control

Our Ethyl 4-Methyl-4-Pentenoate is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing including GC, HPLC, and NMR to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) documenting all specifications are provided and available upon request, supporting compliance in regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, although short-term storage at controlled room temperature (15-25°C) is acceptable.
