88-99-3
Product name: Phthalic Acid
English alias: o-Phthalic acid; 1,2-Benzenedicarboxylic acid; Ortho-phthalic acid
CAS: 88-99-3
Molecular formula: C8H6O4
Appearance:White crystalline powder or crystals
Package: 25kg/drum
Phthalic Acid, chemically known as ortho-phthalic acid or 1,2-benzenedicarboxylic acid, is an aromatic dicarboxylic acid with the molecular formula C₈H₆O₄. It is characterized by two carboxyl groups attached to adjacent carbon atoms on a benzene ring. This compound is primarily produced through the oxidation of naphthalene or ortho-xylene. Phthalic Acid exhibits moderate solubility in water and good solubility in hot water and polar organic solvents. It typically appears as white crystalline needles or powder and serves as a crucial intermediate in the chemical industry, particularly in the production of plasticizers, dyes, and polyester resins.

1.Primary raw material for production of phthalate plasticizers (e.g., DOP, DBP)
2.Key intermediate in manufacturing alkyd resins and polyester polyols
3.Used in synthesis of dyes, pigments and colorants
4.Production of unsaturated polyester resins
5.Manufacturing of pharmaceutical intermediates
6.Used in organic synthesis as a building block
7.Production of insect repellents and antimicrobial agents
8.Intermediate for specialty chemicals and fine chemicals
Phthalic Acid may cause irritation to skin, eyes and respiratory system. It is recommended to use appropriate personal protective equipment including chemical-resistant gloves, safety goggles and dust masks. The compound may form combustible dust concentrations in air. Avoid inhalation of dust and direct contact with skin and eyes. In case of contact, flush immediately with plenty of water. Phthalic Acid is biodegradable under appropriate conditions.
