Pinacol CAS 76-09-5

1. Pinacol CAS 76-09-5 is widely used as a key raw material for preparing synthetic intermediates like pinacolborane, bis(pinacolato)diboron, and pinacolchloroborane by reaction with boron trichloride .
2. Pinacol plays an important role as an intermediate for biologically active compounds, including those with antiviral, antibacterial, antifungal, and antituberculous properties .
3. Applications of Pinacol also include its use as a ligand to prepare uranyl complexes, in the classic pinacol rearrangement reaction to produce pinacolone, and as a reactant in the synthesis of various organic compounds .

1. Store Pinacol CAS 76-09-5 in a tightly sealed container in a cool, dry, well-ventilated place; recommended storage includes room temperature (in a cool, dark place <15°C) or under inert gas (argon) for long-term stability .
2. Keep Pinacol away from strong oxidizing agents, strong bases, and strong acids due to incompatibility; protect from moisture as the compound is hygroscopic .
3. Always Pinacol use appropriate personal protective equipment (PPE) including protective gloves (nitrile rubber recommended) and tightly fitting safety goggles when handling Pinacol to avoid skin, eye, and respiratory contact .

1. Immediately contain the Pinacol spill, avoid dust formation, and use personal protective equipment; prevent material from entering drains or waterways .
2. Carefully sweep up spilled Pinacol solid using clean methods and place the collected material into sealed, labeled chemical waste containers for proper disposal according to local, state, and federal environmental regulations .
3. Personnel Pinacol must wear suitable PPE during cleanup; dispose of Pinacol and all contaminated materials as hazardous waste; note that Pinacol may form explosive dust in air .

1. Pinacol CAS 76-09-5 is classified with a GHS signal word "Warning" and causes skin irritation (H315) and serious eye irritation (H319); it may also cause respiratory irritation (H335) . Some sources also classify Pinacol as a flammable solid (H228) .
2. Pinacol has a flash point of 77°C and is combustible; thermal decomposition produces toxic and irritating fumes including carbon oxides . Dust may form explosive mixtures in air .
3. Pinacol is considered not dangerous goods for transport by some classifications (UN number: Not dangerous goods) , though other sources list RIDADR UN 1325 4.1/PG 2 . It is for R&D use only and not for medicinal, household, or other use . Always consult the specific Safety Data Sheet (SDS) for Pinacol for complete hazard information, first-aid procedures, and handling instructions .
