Description

2-Hydroxybenzophenone (CAS NO 117-99-7) is a versatile organic compound belonging to the benzophenone class, valued for its ability to absorb ultraviolet light. This property makes it a critical intermediate and functional additive in industries requiring UV stabilization and protection. It is essential for manufacturers in the polymer, coatings, and specialty chemical sectors seeking to enhance product durability and performance.

Application

• UV Stabilizer and Light Absorber: A key intermediate in the synthesis of advanced UV absorbers (UVA) and hindered amine light stabilizers (HALS) for plastics and polymers.
• Polymer Industry: Used to produce additives that protect polyolefins (PP, PE), PVC, coatings, and adhesives from photodegradation, preventing yellowing and loss of mechanical strength.
• Coatings and Inks: Incorporated into formulations for automotive, industrial, and wood coatings to improve weatherability and gloss retention.
• Personal Care & Sunscreens: Serves as a precursor for UV-filtering agents used in sunscreen formulations to protect against UVA/UVB radiation.
• Pharmaceutical Intermediates: Utilized in the synthesis of certain active pharmaceutical ingredients (APIs) and other fine chemicals.
• Organic Synthesis: Acts as a building block in various organic reactions, including the production of dyes, pigments, and photoinitiators.
