Phthalic acid diammoniate(CAS: 523-24-0)

Phthalic acid diammoniate, also known as diammonium phthalate (DAP), is a white crystalline solid with the chemical formula (NH4)2C4H4O4. It is widely used in various applications due to its stability and solubility in water. DAP is commonly used as a plasticizer, a stabilizer, and a pH buffer in industrial and laboratory settings.

Phthalic acid diammoniate (DAP) is primarily used as a plasticizer in the manufacturing of plastics and rubbers, as a stabilizer in the production of polyvinyl chloride (PVC), and as a pH buffer in pharmaceuticals and food industries. It also serves as a molecular sieve in analytical chemistry and as a water treatment agent.

Phthalic acid diammoniate (DAP) is generally considered safe for its intended uses. However, it is important to follow proper handling procedures, including wearing appropriate personal protective equipment such as gloves and goggles. Exposure to high temperatures or prolonged contact with skin should be avoided to prevent any potential irritation or adverse effects.

Phthalic acid diammoniate (DAP) should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a sealed container to prevent moisture absorption, which can affect its stability. The storage temperature should not exceed 25°C (77°F) to maintain its quality and effectiveness.
