Product Properties

This aromatic acyl chloride compound exists as uniform crystalline powder at room temperature. It dissolves well in polar organic solvents including DMF and dichloromethane, with extremely low solubility in water. The coexisting anhydride ring and acyl chloride group endow it high reactivity toward amines, alcohols and epoxy groups. It undergoes hydrolysis upon exposure to moisture, so airtight dry storage is required to maintain structural integrity. Its rigid benzene ring backbone contributes to outstanding heat resistance of final polymer products.

Main Applications

Core synthetic monomer for polyimide and polyamide-imide engineering plastics
Crosslinking monomer for high-temperature resistant insulating varnishes and specialty coatings
Curing agent and modifier for epoxy resin systems
Research reagent for functional polymer development in laboratory scenarios

Q1: What precautions apply to storage and handling?

A: The product is susceptible to hydrolysis in humid conditions. Store in tightly sealed containers under dry cool surroundings, and avoid direct contact with water and strong oxidizing substances.

Q2: Can supporting test documents be provided?

A: Certificate of Analysis, HPLC purity report and safety data sheet are available upon formal request.

Q3: Is it suitable for aqueous reaction systems?

A: The acyl chloride group decomposes in aqueous environments. Anhydrous organic solvent systems are recommended for relevant reactions.
