Chimassorb 944(CAS: 71878-19-8)

Chimassorb 944, with the CAS number 71878-19-8, is a chemical compound used primarily as a photostabilizer. It has the chemical formula C19H22O3 and is known for its ability to absorb ultraviolet (UV) light, thereby protecting materials from degradation. It is a white to off-white solid with low solubility in water and is commonly used in polymer applications to enhance durability and color stability.

Chimassorb 944 is widely used in the plastics and polymer industry as a UV stabilizer to prevent yellowing and degradation caused by sunlight. It is also applied in pharmaceuticals, coatings, and adhesives to improve product longevity. Its effectiveness in blocking UV radiation makes it a valuable additive in various industrial and consumer products, including those requiring long-term stability and protection.

Chimassorb 944 is considered safe when used as directed, with low toxicity and minimal risk to human health. It meets international safety standards for use in consumer and industrial products. However, proper handling precautions should be followed, such as wearing gloves and ensuring adequate ventilation, to minimize exposure during application or manufacturing.

Chimassorb 944 should be stored in a cool, dry, and dark place to maintain its stability and effectiveness. It is best kept in a sealed container away from moisture and direct light. Storage conditions should be controlled to prevent degradation, and it is typically stable under normal industrial storage conditions when properly handled.
