2,5-Diaminoterephthalic acid(CAS: 945-30-2)

2,5-Diaminoterephthalic acid (2,5-DiA) is a white crystalline solid with a molecular weight of 196.16 g/mol. It has a solubility of approximately 0.25 g/L in water at 25°C. Chemically, it is highly reactive, particularly with carboxylic acids and amines.

2,5-Diaminoterephthalic acid is typically synthesized via the amino-tungstic acid route, involving the reaction of tungstic acid with primary amines. This process yields the target compound with good selectivity and moderate to high yield.

2,5-Diaminoterephthalic acid finds applications in the pharmaceutical and polymer industries. It is used as a raw material for the synthesis of various dyes, pharmaceuticals, and polyamides due to its unique chemical properties.

When handling 2,5-Diaminoterephthalic acid, it is essential to use personal protective equipment (PPE) such as gloves and goggles. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate methods and materials, and the substance should be stored in a cool, dry place away from direct sunlight. Refer to the safety data sheet (SDS) for detailed safety information.
