Description

2,2'3,4,4'-Pentahydroxy Benzophenone is a multi-hydroxylated benzophenone derivative, a compound class known for its potent antioxidant and UV-absorbing properties. This specific polyhydroxy structure is highly valued for its ability to act as a free radical scavenger and metal chelator, providing stability in sensitive formulations. It is primarily sought by manufacturers in the cosmetics, pharmaceutical, and specialty polymer industries for advanced stabilization and functional additive applications.

Application

• Cosmetic & Personal Care Stabilizer: Used as a high-performance antioxidant and UV filter in sunscreens, anti-aging creams, and lotions to protect formulations and skin from oxidative damage.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of more complex molecules with therapeutic potential, particularly those requiring a polyphenolic core.
• Polymer Additive: Functions as a light stabilizer and antioxidant in specialty plastics, coatings, and adhesives to prevent yellowing and degradation.
• Research & Development: Employed in biochemical and material science research to study antioxidant mechanisms, chelation chemistry, and photostability.
• Food Packaging Material: Incorporated into active packaging films to enhance shelf-life by scavenging oxygen and free radicals.

Quality Control

Our 2,2'3,4,4'-Pentahydroxy Benzophenone is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
