Sodium borohydride is a powerful reducing agent widely used in organic synthesis, pharmaceuticals, and analytical chemistry to reduce carbonyl compounds, aldehydes, ketones, and imines. It is a white crystalline solid that reacts vigorously with water and acids, requiring careful handling. Industrially, it also serves as a bleaching agent for wood pulp in papermaking, a blowing agent for plastics, and a reagent for recovering gold and platinum group metals. CAS 16940-66-2, molecular formula H₄BNa, molecular weight 37.83 g/mol. Store at ambient temperature in a dry, inert atmosphere. Signal word: Danger. Molekula supplies sodium borohydride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
