Quality Control

Our 2-(3-Bromophenyl)-4-Pentyn-2-Ol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
