INTRODUCTION

Potassium borohydride (KBH4) is an inorganic chemical with unique reducing power that is used in chemical synthesis. Whereas it easily generates a hydrogen atom quintessential for reduction processes, the borohydride reacts violently with water. It is toxic by ingestion. KBH4 finds large consumption in agrochemicals, pharmaceuticals, and intermediates.

Manufacture

KBH4 is conveniently produced by reaction of caustic potash with sodium borohydride.

SynonymPotassium Tetrahydroborate
CAS no.13762-51-1

Molecular weight53.94
Structure

Applications in Pharma

Potassium borohydride finds application in production of many APIs including:
Fenfluramine
Zopiclone
Fluoxetine
Gliclazide
Trimebutine maleate

Applications in Agrochemicals

The borohydride is further employed in synthesis of agrochemicals such as:
Diniconazole
Bromhexine HCl
Triadimenol
Bromadiolone
Paclobutrazol
Brodifacoum

Applications in Intermediates

For its excellent reduction prowess, the molecule converts organics acids, aldehydes, and ketones to corresponding alcohols, whereby a large array of intermediates can be produced. Besides, the borohydride is found to have usage in production of diethylamine borane, dimethylamine borane, and sodium hydrosulphite.
