5 5′-Methylenebis(2-aminobenzoic Acid) / MBAA CAS 7330-46-3

1. Acts 5 5′-Methylenebis(2-aminobenzoic Acid) as a bifunctional monomer for synthesizing high-strength polyamides and polyimide resins with excellent thermal and mechanical properties.
2. Serves MBAA CAS 7330-46-3 as a crosslinking agent for epoxy resins to improve adhesion, chemical resistance and flame retardancy of cured products.
3. Functions as a building block for preparing pharmaceutical intermediates and metal-chelating ligands with dual carboxyl and amino groups.

Store MBAA CAS 7330-46-3 at 5–25℃ in sealed HDPE/amber glass drums in a cool, dry, well-ventilated area, away from light, strong oxidants and acids. Wear nitrile gloves, safety goggles and a dust mask; avoid inhalation, skin/eye contact & ingestion (mild irritant). Reseal tightly post-use to prevent moisture absorption; dispose of waste via licensed chemical waste channels.
