  • Applications

    Bromotrifluoromethane, CAS 75-63-8, is a halogenated fire-extinguishing agent primarily used in total-flooding systems for electrical and electronic equipment, with data centers and telecom facilities as typical environments; it has historically been deployed in aerospace, marine, and industrial facilities to protect critical infrastructure and sensitive gear from fire; due to environmental concerns and regulatory phase-down, its use is increasingly restricted and alternatives with lower environmental impact are adopted; handling and deployment are subject to local regulations and formulation limits, and modern practice often relies on newer clean agents.
