1. Phosphorus tribromide CAS 7789-60-8 is commonly used to convert alcohols to alkyl bromides in organic synthesis.

2. Phosphorus tribromide serves as a reagent for brominating carboxylic acids to form acyl bromides.

3. Additionally, Phosphorus tribromide CAS 7789-60-8 is employed in deoxygenation reactions of certain organic compounds.

1. Store Phosphorus tribromide in a tightly sealed, moisture-free container under an inert atmosphere (e.g., nitrogen) to prevent hydrolysis, Phosphorus tribromide produces toxic hydrogen bromide gas.

2. Keep Phosphorus tribromide CAS 7789-60-8 in a cool, well-ventilated area, away from water, alcohols, and strong bases, as Phosphorus tribromide reacts violently with these substances.

3. Ensure proper labeling and handle with protective gear, as Phosphorus tribromide is corrosive and Phosphorus tribromide fumes can cause severe respiratory and skin irritation.
