Sodium borohydride (NaBH₄) is a chemical compound commonly used as a reducing agent in organic chemistry and industrial applications. It is a white, crystalline powder that is highly reactive and is known for its ability to reduce a wide variety of functional groups, especially carbonyl compounds like aldehydes and ketones.

Sodium Borohydride Powder

• Brand: DAEJUNG
• Pack Size: 100g
• Chemical Formula: NaBH₄
• Made in Korea

Properties of Sodium Borohydride Powder:

• Molecular Formula: NaBH₄
• Appearance: White crystalline powder
• Solubility: Soluble in water and ethanol, but relatively insoluble in nonpolar solvents.
• Stability: Sodium boro-hydride is relatively stable under normal conditions, but it reacts readily with water and acids to release hydrogen gas.
• Odor: Odorless.

Common Uses:

1. Reduction of Aldehydes and Ketones:
   • NaBH₄ is widely used in the reduction of aldehydes and ketones to their corresponding alcohols.
2. Reduction of Esters and Amides:
   • In some cases, sodium borohydride can reduce esters and amides to alcohols or amines, though this requires more specific conditions or catalysts.
3. Selective Reduction:
   • It is often used when selective reduction is required because it typically reduces carbonyl groups without affecting other functional groups, like double bonds.
4. Organic Synthesis:
   • It plays a key role in organic synthesis, especially in the production of pharmaceuticals, fragrances, and other chemicals.
5. Fuel Cells:
   • Sodium borohydride is also used in some fuel cell technologies as a hydrogen source, where it reacts with water to release hydrogen gas.

Reactivity and Safety:

• Reaction with Water: Sodium borohydride reacts with water, releasing hydrogen gas (H₂), which can be explosive in confined spaces. This makes handling sodium borohydride in aqueous solutions potentially hazardous.
• Handling: Due to its reactivity with moisture, it should be stored in a dry, airtight container. Always use gloves and eye protection when handling sodium borohydride, and work in a well-ventilated area.
• Incompatible Materials: Sodium borohydride is incompatible with strong acids, moisture, and oxidizing agents.

Safety Notes:

• Inhalation/Exposure: Prolonged exposure to sodium borohydride dust or fumes may be harmful. Proper respiratory protection is advised when handling the compound in large amounts.
• Skin Contact: This can irritate, so gloves should be worn to avoid direct contact.
• Storage: Store in a cool, dry place, away from heat sources, moisture, and incompatible substances.
