1. Acts 4-Chlorobenzophenone CAS 134-85-0 as a high-efficiency photoinitiator in UV-curable coatings and inks, accelerating polymerization reactions for fast curing of printing and coating products.

2. Serves 4-Chlorobenzophenone as a core pharmaceutical intermediate, supporting the synthesis of lipid-lowering drugs and antihistamine pharmaceutical raw materials stably.

3. Functions as an organic synthesis building block, facilitating the preparation of functional dyes, pesticide intermediates and polymer modifiers effectively.

Store 4-Chlorobenzophenone (CAS 134-85-0, white crystalline powder, faint aromatic odor, flash point 143°C, combustible, mp 93-96℃) at 10–25°C in sealed amber glass/HDPE containers in a cool, dry, well-ventilated area. Isolate from strong oxidants, acids and alkalis 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 aromatic ketone & fine chemical regulations.

4-Chlorobenzophenone is an industrial photoinitiator and synthetic intermediate, not for direct pure-form human contact or ingestion; undiluted contact may cause skin and mucosal irritation, and intake will lead to gastrointestinal discomfort. In regulated applications, 4-Chlorobenzophenone  features excellent UV photosensitivity and stable chemical reactivity, ensures high-efficiency curing of UV formulations, and provides reliable performance for pharmaceutical and fine chemical synthesis.
