Buy Phosphorus Pentoxide (P₂O₅) – Properties, Safety & Applications

Are you looking for high-quality phosphorus pentoxide for laboratory or industrial use? Phosphorus pentoxide, also known as diphosphorus pentaoxide, is a powerful desiccant and reagent that is widely used in chemical syntheses and production processes. With us, you can buy P₂O₅ easily, quickly, and safely – with guaranteed quality and competitive prices.

Properties of Phosphorus Pentoxide

Phosphorus pentoxide (chemical formula P₂O₅) is a white, crystalline solid that is highly hygroscopic. This means it absorbs and binds water vapor from the air. As a result, it is one of the most effective desiccants available.

Key properties of phosphorus pentoxide include:

• Chemical formula: P₂O₅

• Molar mass: 141.94 g/mol

• Appearance: white, powdery crystal

• Solubility: reacts violently with water, releasing heat

• Melting point: decomposes upon heating, no classical melting point

• Reactivity: reacts with water to form phosphoric acid (H₃PO₄)

Thanks to these unique properties, phosphorus pentoxide is indispensable in many chemical and industrial applications.

Safety When Using Phosphorus Pentoxide

Phosphorus pentoxide is a corrosive and reactive substance, so caution is essential when handling it. Contact with moisture or water generates heat and corrosive phosphoric acid.

Safety measures:

• Always work in a well-ventilated area or fume hood.

• Wear protective clothing, gloves, and safety goggles.

• Avoid contact with skin, eyes, and respiratory system.

• Store in tightly sealed, moisture-free containers to prevent exposure to humidity.

In case of spills or accidental contact, rinse immediately with plenty of water and seek medical attention.

Applications of Phosphorus Pentoxide

Phosphorus pentoxide is used in a wide range of industries due to its strong drying and reactive properties:

As a desiccant

Used to dry organic solvents and gases, as it absorbs moisture extremely effectively.

In the chemical industry

An essential raw material for the production of phosphoric acid and other phosphorus compounds.

Organic synthesis

Employed as a dehydrating reagent in condensation reactions and in the synthesis of specific organic compounds.

Pharmaceutical applications

Used in specialized processes for the preparation of active pharmaceutical ingredients (APIs).

Laboratory use

Commonly applied in analytical and research settings as a desiccant or catalyst in chemical reactions.
