Quality Control

Our 5-Phenyl-2,4-pentadienoic acid chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are 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 2-8°C under an inert atmosphere (e.g., nitrogen or argon). Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed and handled under dry conditions to prevent hydrolysis. Keep away from strong bases, oxidizers, and sources of ignition.
