Product Description

The proven, high-performance reagent from LANXESS that sets the standard for precision in industrial and fine-chemical synthesis. With DIBAH you benefit from unmatched selectivity, reliable batch-to-batch consistency, and broad applicability — ideal when you need controlled, reproducible results for polymers, pharma, or specialty chemicals.

 

THESE SPECIAL FEATURES MAKE THIS PRODUCT SO SUCCESSFUL

  • Exceptional chemoselectivity: DIBAH reduces esters and nitriles selectively to aldehydes under controlled conditions, where many other reductants would over-reduce to alcohols.
  • Controlled reactivity: Its bulky iso-butyl groups ensure that only sterically accessible, electrophilic centers are attacked — making it ideal for complex, multifunctional molecules.
  • Broad reduction scope: Beyond esters and nitriles, DIBAH can reduce ketones, lactones or acids under appropriate conditions, offering flexibility to chemists.
  • Versatility in formulation: Available commercially both as neat reagent and as solutions (e.g. in toluene), facilitating safe handling and integration into different process workflows.
  • Industrial-grade quality & reliability: Supplied by LANXESS with high purity and consistent performance — ensuring reproducibility and minimizing by-products even under demanding synthesis conditions.

 

THE MOST COMMON AREAS OF APPLICATION

  • Selective reduction of esters and nitriles to aldehydes — often a critical intermediate step in pharmaceutical and fine-chemical synthesis.
  • Reduction of ketones, lactones or carboxylic-acid derivatives when mild, controlled reduction is required.
  • Co-catalyst or reagent in polymerization processes (e.g., in rubber or polymer industries), where precise control over molecular structure is needed.
  • Use in fine chemicals and specialty chemicals production — including dyestuffs, agrochemical intermediates, and other advanced materials.
  • Application in pharmaceutical and active-ingredient synthesis, particularly when high selectivity and minimal side reactions are essential.
