Description

Phthalic Acid 1-Allyl 2-Sodium Salt is a specialized organic salt derived from phthalic acid, featuring both an allyl group and a sodium carboxylate moiety. This unique structure makes it a valuable intermediate and functional additive in advanced polymer synthesis and specialty chemical manufacturing. It is primarily sought by R&D laboratories and industrial producers in the polymer, coatings, and adhesive sectors seeking to modify material properties or introduce reactive sites.

Application

• As a reactive monomer or co-monomer in the synthesis of specialty polyesters and alkyd resins.
• As a functional additive in coating formulations to enhance adhesion, flexibility, or cross-linking density.
• As an intermediate in the production of plasticizers, stabilizers, or other performance chemicals.
• In research and development for creating novel polymers with tailored thermal or mechanical properties.
• Potential use in the formulation of advanced adhesives and sealants.
• As a building block in organic synthesis for pharmaceuticals or agrochemicals.

Quality Control

Our Phthalic Acid 1-Allyl 2-Sodium Salt is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with every shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
