Understanding the specific spectral properties of chemical compounds is vital for formulators and researchers aiming to optimize material protection. 2,4-Dihydroxybenzophenone (CAS: 131-56-6) is a highly effective UV absorber, and its performance is directly tied to its unique UV absorption spectrum. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer, provides insight into why this compound is so critical for UV protection.

2,4-Dihydroxybenzophenone is particularly valued for its strong absorption in the UV-B range, typically between 280 nm and 320 nm. This band of the UV spectrum is known to be the most damaging to many organic materials, causing photodegradation that leads to discoloration, loss of physical properties, and reduced lifespan. The compound efficiently absorbs this high-energy radiation, converting it into harmless thermal energy, thus shielding sensitive polymers, coatings, and other substrates.

For professionals looking to buy chemical intermediates with predictable performance, the specific extinction coefficient at key wavelengths is important. While exact figures vary slightly based on solvent and concentration, 2,4-Dihydroxybenzophenone consistently shows high absorbance values in the critical UV-B region. This characteristic makes it an essential component for anyone seeking to purchase materials that require robust protection against sunlight.

The effectiveness of 2,4-Dihydroxybenzophenone as a light stabilizer is further enhanced by its good compatibility with a wide array of polymers. This means that when you buy this UV absorber from NINGBO INNO PHARMCHEM CO.,LTD., you can confidently incorporate it into formulations for plastics, coatings, and adhesives, knowing it will effectively protect these materials. Its ability to prevent yellowing in polystyrene or improve the optical properties of polymethacrylates is directly attributed to its precise UV absorption capabilities.
