This compound is a high-value bicyclic hydroxyl ester monomer widely used in polymer, pharmaceutical, and fine chemical industries. It serves as a key intermediate for synthesizing norbornene-based polymers, offering excellent reactivity in ring-opening metathesis polymerization (ROMP) and radical polymerization to prepare high-performance resins with high glass transition temperature, low dielectric constant, and good mechanical strength. In pharmaceuticals, it acts as a critical building block for synthesizing antiviral, anti-inflammatory, and central nervous system drugs, especially for constructing bridged-ring structures in active pharmaceutical ingredients (APIs). It is also used in electronic materials as a monomer for photoresists and encapsulation resins, providing good adhesion and heat resistance. Additionally, it functions as a cross-linking agent and modifier in coatings, adhesives, and daily chemicals, enhancing product durability and weather resistance.

This substance is classified as a low-to-moderate hazard chemical with GHS07 labeling (Warning). It may cause acute toxicity (H302) if swallowed, skin irritation (H315), serious eye irritation (H319), and respiratory irritation (H335). Avoid inhalation of vapors or mist; use in a well-ventilated area with local exhaust. Wear nitrile gloves, safety goggles, and a dust mask during handling to prevent skin, eye, and respiratory contact. In case of skin contact, wash immediately with plenty of soap and water; for eye contact, rinse with water for at least 15 minutes and seek medical attention if irritation persists. Store away from oxidizing agents, strong acids, and heat sources. Spills should be absorbed with inert materials (sand, earth) and disposed of as hazardous waste; prevent entry into drains or waterways to avoid environmental harm.
