2 3-Naphthalenedicarboxylic Acid CAS 2169-87-1

1. Acts as a key monomer for synthesizing high-performance polyesters and polyamides with excellent thermal stability.
2. Serves 2 3-Naphthalenedicarboxylic acid CAS 2169-87-1 as a building block in organic synthesis for preparing naphthalene-based dyes and fluorescent materials.
3. Functions as a reagent in analytical chemistry for detecting metal ions via complexation reactions in aqueous systems.

1. Store in sealed containers at 15-25℃ in a cool, dry, dark area away from moisture, strong bases, and oxidizing agents.
2. Keep 2 3-Naphthalenedicarboxylic acid separated from amines and alcohols to prevent premature esterification or amidation reactions during storage.
3. Wear nitrile gloves, safety goggles, and a lab coat during handling to avoid skin contact and dust inhalation.

1. The fused naphthalene ring structure enhances the rigidity and thermal resistance of derived polymer materials.
2. Dual 2 3-Naphthalenedicarboxylic acid carboxylic acid groups provide multiple reactive sites for efficient polymerization and functionalization reactions.
3. Good solubility in polar solvents like DMF and DMSO simplifies formulation and processing for industrial applications.
