POLYSTYRENE SULFONIC ACID(CAS: 28210-41-5)

Polystyrene sulfonic acid is a water-soluble polymer acid derived from polystyrene. Its chemical formula is (C8H7SO3)k. It is characterized by its high carboxyl content, which makes it an excellent anion exchanger and surfactant.

Polystyrene sulfonic acid is primarily used as an ion-exchange resin, a surfactant, and a component in various chemical and pharmaceutical applications. It is also used in the synthesis of polymers, in electrochemical cells, and as a stabilizer in food products.

Polystyrene sulfonic acid is classified as non-toxic, but it can cause skin irritation and should be handled with gloves. It is important to follow safety standards, such as avoiding contact with skin and eyes, and storing it in a well-ventilated area. Personal protective equipment should be used during handling.

Polystyrene sulfonic acid 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. Avoid storing it in close proximity to flammable materials. Maintain a temperature range of 15°C to 25°C and humidity below 50%.
