Description

Sodium Tetrahydroborate, also known as sodium borohydride, is a versatile and powerful inorganic reducing agent with the CAS number 16940-66-2. Its primary value lies in its ability to selectively reduce aldehydes, ketones, and acid chlorides under mild conditions, making it indispensable for controlled synthesis. This compound is a critical raw material for research laboratories and industrial-scale production processes across several high-value sectors.

Application

• Pharmaceutical Synthesis: Key reagent for the reduction of intermediates in the production of active pharmaceutical ingredients (APIs), including steroids and antibiotics.
• Fine Chemical & Specialty Manufacturing: Used in the synthesis of perfumes, flavors, and other complex organic molecules requiring selective reduction steps.
• Pulp & Paper Industry: Employed as a bleaching agent and for the reduction of colorants in wood pulp processing.
• Wastewater Treatment: Acts as a reducing agent for the detoxification of heavy metals like mercury and chromium, converting them into less harmful, insoluble forms.
• Organic Synthesis & Research: A staple reagent in academic and industrial R&D labs for hydrogenation, dehalogenation, and other reductive transformations.
• Fuel Cell Technology: Investigated as a potential hydrogen storage material due to its high hydrogen content.
