1. Acts Methyl 2-benzoylbenzoate as a high-efficiency photoinitiator in UV-curable coatings and inks, accelerating polymerization reactions to realize fast curing of plastic and metal surface coatings.

2. Serves Methyl 2-benzoylbenzoate CAS 606-28-0 as a UV absorber in polymer processing, effectively preventing yellowing and aging of plastics and rubber products caused by ultraviolet radiation.

3. Functions as a key organic synthesis intermediate, supporting the preparation of pharmaceutical raw materials, functional dyes and fine chemical derivatives stably.

Store Methyl 2-benzoylbenzoate (CAS 606-28-0, white crystalline powder, mp 48-53℃, bp 352℃, density 1.69g/cm³) at 10–25℃ in sealed amber glass/HDPE containers in a cool, dry, dark and well-ventilated area. Isolate from strong oxidants, acids and direct sunlight to avoid decomposition and discoloration. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local UV absorber & hazardous chemical regulations.

Methyl 2-benzoylbenzoate is an industrial photoinitiator, UV absorber and synthetic intermediate, not for direct pure-form human contact or ingestion; undiluted contact may cause skin and mucosal irritation, and accidental intake will lead to gastrointestinal discomfort. In regulated applications, Methyl 2-benzoylbenzoate CAS 606-28-0 features excellent UV absorption and photosensitivity, has good compatibility with polymer and coating systems, and exhibits stable chemical properties under normal processing and storage conditions.
