1-hydroxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate)

1-hydroxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) is classified as explosive. Storage must comply with national explosives regulations — only in approved explosive storage magazines, away from all ignition sources, heat, and friction. Quantities must be minimised and access restricted to authorised personnel only.

1-hydroxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) is corrosive to skin, eyes, or metals. Store in acid-resistant or alkali-resistant cabinets as appropriate. Do not store in metal containers. Secondary containment (drip trays) is required. Segregate from incompatible substances such as strong oxidisers.

1-hydroxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) may cause irritation to skin, eyes, or respiratory tract, or has low-level systemic toxicity. Adequate ventilation must be provided in work areas. Personal protective equipment (gloves, eye protection) is recommended during handling.

1-hydroxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) is classified as a specific target organ toxicant (STOT). Exposure must be minimised using engineering controls (local exhaust ventilation, closed systems). Biological and medical monitoring may be required. Refer to the full Safety Data Sheet (SDS) Section 8 for occupational exposure limits.

1-hydroxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) is hazardous to the aquatic environment. Do not allow this substance to enter drains, waterways, or soil. Spills must be contained immediately using appropriate absorbent material. Disposal must comply with local environmental regulations — consult the SDS Section 13 for guidance on waste treatment.

This substance carries the signal word DANGER, indicating the more severe hazard categories under GHS/CLP. Facilities handling 1-hydroxy-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) should ensure a written hazard communication programme, including current SDS, employee training records, and GHS-compliant labelling on all containers.
