Aluminium sodium phosphate (1:3:2)(CAS: 7785-88-8)

Aluminium sodium phosphate (1:3:2) (CAS: 7785-88-8) is a crystalline compound with a molecular weight of approximately 492.43 g/mol. It is moderately soluble in water and slightly soluble in dilute acids. The compound shows low reactivity under normal conditions, but it can form insoluble salts with some heavy metals. It has a characteristic pH of around 7.5, which makes it slightly basic.

Aluminium sodium phosphate (1:3:2) (CAS: 7785-88-8) is typically synthesized through a precipitation reaction between aluminium and sodium phosphates in aqueous solution. The reaction is usually conducted at room temperature, and the precipitate is then filtered, washed, and dried. Ammonium or sodium hydroxide is often used as a precipitating agent to control the pH and improve the yield and purity of the product.

Aluminium sodium phosphate (1:3:2) (CAS: 7785-88-8) is used in various industries including pharmaceuticals, where it acts as a buffering agent, in polymers as a flame retardant, and in sensors for pH and ion detection. It also finds applications in semiconductor processing as a precursor for phosphorus-doped materials.

When handling Aluminium sodium phosphate (1:3:2) (CAS: 7785-88-8), it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. The compound should be stored in a dry, well-ventilated area, away from strong acids and reducing agents. In case of a spill, it should be carefully cleaned up using appropriate absorbents, and the area should be well-ventilated. Safety data sheets (SDS) should be consulted for detailed handling and disposal procedures.
