Sodium borohydride

Sodium borohydride (CAS 16940-66-2), commonly abbreviated as NaBH4, is a selective reducing agent used in chemical manufacturing, precious metals recovery, and industrial processing.

Where is Sodium borohydride used?

• Pharmaceutical manufacturing: reduces ketones and aldehydes to alcohols in active pharmaceutical ingredient synthesis
• Precious metals recovery: precipitates gold, silver, and platinum-group metals from leach solutions, improving yield in mining and refining circuits
• Pulp and paper: bleaching stabilizer protecting brightness gains during hydrogen peroxide bleaching stages
• Textile and leather: reductive finishing baths fix dyes
• It delivers controlled reduction reactions under mild conditions.

Good to know: Offers a safer and more scalable alternative to other hydride reagents. Reductive finishing baths help reduce residual chromium in effluent and meet discharge compliance targets.

Commercial specifications
