Fluorescent Brightener 220, Technical Grade(CAS: 16470-24-9)

Fluorescent Brightener 220 (CAS: 16470-24-9) is a crystalline compound with a molecular weight of approximately 434.5 g/mol. It has limited solubility in water but is soluble in common organic solvents like ethanol and acetone. Chemically, it exhibits good stability but can react with acidic or basic substances, making it important to handle in a controlled environment.

Fluorescent Brightener 220 is synthesized through a multistep process involving the condensation of aromatic compounds. The reaction typically requires a catalyst such as a Lewis acid to promote the coupling of substrates. The process yields around 85% of the desired product, making it a reliable method for commercial production.

Fluorescent Brightener 220 is widely used in the textile and paper industries to enhance the brightness and whiteness of fabrics and paper products. It is also employed in the plastics industry to improve the visual appearance of plastic materials.

When handling Fluorescent Brightener 220, it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or use a fume hood to prevent inhalation. In case of a spill, neutralize the area with an appropriate neutralizing agent and clean up using gloves. Always consult the Safety Data Sheet (SDS) for detailed safety information.
