Quality Control

Our 4-Bromo-2-Heptene is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including GC, HPLC, and NMR to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment. Our quality system is designed to meet the stringent requirements of research and process development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place, 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. Keep under an inert atmosphere if specified for high-purity grades.
