Description

4-Chlorophenyl Glycidyl Ether is a reactive aromatic glycidyl ether widely used as a chemical intermediate and epoxy resin modifier. It imparts enhanced thermal stability, hydrophobicity, and adhesion to epoxy systems while maintaining low viscosity and excellent reactivity with amines and anhydrides. This compound is essential for manufacturers developing high-performance coatings, electrical encapsulants, composite matrices, and specialty adhesives serving aerospace, electronics, and industrial OEM markets. Its versatility in formulating advanced thermosets makes it a strategic raw material for global chemical processors and polymer formulators.

Application

• Reactive diluent and flexibilizer in bisphenol-A and novolac epoxy resins for printed circuit board (PCB) laminates and underfill materials
• Chemical intermediate for synthesizing chlorinated aryl-containing epoxy monomers and oligomers
• Surface modifier for carbon fiber and glass fiber reinforcements to improve interfacial bonding in structural composites
• Crosslinker component in high-gloss, UV-resistant automotive clearcoats and industrial maintenance coatings
• Building block in the synthesis of flame-retardant epoxy curing agents (e.g., chlorinated amine adducts)
• Functional additive in photoresist formulations requiring controlled polarity and etch resistance
• Monomer for specialty polyglycidyl ether-based ion-exchange resins and chromatographic supports
• Stabilizer and compatibilizer in halogen-free flame-retardant epoxy–phosphinate hybrid systems

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches are tested per ASTM D4294 (XRF for chlorine content), USP <851> (epoxide assay), and ISO 9001-certified protocols. Purity verification is performed using HPLC with UV detection, and residual solvent profiling follows ICH Q3C guidelines. Compliance with REACH Annex XIV and FDA 21 CFR 175.300 (indirect food contact) is verified for applicable grades.

Storage

Preserve in a tightly closed container, protected from light. Store at 15–25°C in a dry, well-ventilated area. Due to its hygroscopic nature, minimize exposure to ambient humidity during handling. Avoid contact with strong acids, strong alkalis, and oxidizing agents.
