Terephthalic acid(CAS: 100-21-0)

Terephthalic acid, with the CAS number 100-21-0, is an aromatic dicarboxylic acid commonly used as a precursor in the production of polyethylene terephthalate (PET). Its chemical formula is C8H6O4, and it is a white crystalline solid with a melting point of approximately 300°C. It is soluble in organic solvents and has acidic properties, making it important in various chemical reactions and industrial processes.

Terephthalic acid (CAS: 100-21-0) is widely used in the manufacturing of polyester fibers, plastic bottles, and films. It also serves as a key component in the production of pharmaceuticals, dyes, and other specialty chemicals. Additionally, it is utilized in the synthesis of polyurethanes and as a raw material in research and development for new materials and compounds.

Terephthalic acid (CAS: 100-21-0) is generally considered safe when handled properly. However, it can be harmful if inhaled, ingested, or comes into contact with the skin. Protective measures such as gloves, goggles, and proper ventilation are recommended. Safety standards ensure its controlled use in industrial and research settings to minimize exposure risks.

Terephthalic acid (CAS: 100-21-0) should be stored in a cool, dry, and well-ventilated place, away from moisture and direct sunlight. It is best kept in sealed, airtight containers made of materials like polyethylene to prevent degradation. Storage conditions should maintain a temperature below 25°C and low humidity to preserve its chemical stability and prolong shelf life.
