3-Bromocyclobutanone CAS 23761-24-2

1. 3-Bromocyclobutanone is primarily used as a specialized building block in organic synthesis for constructing complex molecules, particularly in pharmaceutical and agrochemical research .
2. 3-Bromocyclobutanone CAS 23761-24-2 serves as a key intermediate for preparing 2-bromo-5,8-dioxaspiro[3.4]octane and other spirocyclic compounds with potential biological activity .
3. 3-Bromocyclobutanone is employed as a reactive synthon in the synthesis of cyclobutane-containing natural product analogs and conformationally constrained drug candidates .
4. Researchers utilize 3-Bromocyclobutanone CAS 23761-24-2 for R&D purposes only, leveraging its strained four-membered ring system and reactive bromine for selective functionalization in medicinal chemistry programs .

1. 3-Bromocyclobutanone must be stored in a tightly sealed container under inert atmosphere (nitrogen or argon) in a freezer at -20°C or below to maintain stability .
2. 3-Bromocyclobutanone CAS 23761-24-2 is classified with hazard statements H302 (Harmful if swallowed), H317 (May cause allergic skin reaction), and H319 (Causes serious eye irritation), requiring careful handling protocols .
3. Personnel must wear chemical-resistant gloves, tightly fitting safety goggles with side-shields, face protection, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Avoid formation of dust and aerosols, use 3-Bromocyclobutanone CAS 23761-24-2 spark-proof tools and explosion-proof equipment, keep away from strong oxidizing agents, and wash thoroughly after handling .

1. Isolate the spill area, ensure adequate ventilation, remove all sources of ignition, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and appropriate respiratory protection when 3-Bromocyclobutanone is released .
2. Collect 3-Bromocyclobutanone CAS 23761-24-2 using spark-proof tools by sweeping or vacuuming without creating dust, or absorb with inert materials such as diatomite or universal binders, and place into suitable closed containers for disposal .
3. Avoid creating dust or vapor clouds during cleanup to prevent respiratory exposure, decontaminate surfaces using appropriate methods, and prevent the product from entering drains or water courses due to potential environmental hazards .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration with flue gas scrubbing .

1. 3-Bromocyclobutanone is not classified as highly flammable but may decompose under fire conditions, with a flash point of approximately 111°C (calculated), emitting toxic fumes including carbon monoxide, carbon dioxide, and hydrogen bromide .
2. Use 3-Bromocyclobutanone CAS 23761-24-2 dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product, selecting appropriate extinguishing media based on surrounding environment .
3. Firefighters should wear self-contained breathing apparatus and full protective gear when handling burning 3-Bromocyclobutanone due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray, and contain fire runoff to prevent environmental contamination .
