Quality Control

Our cis-1-Ethyl-2-Methylcyclopentane is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to verify identity, isomeric purity, and chemical composition. Certificates of Analysis (COA) detailing all test results are provided to ensure full traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for long-term stability.
