Use & Application
Industrial grade sodium borohydride solution is mainly used for wastewater treatment and electroplating industry. It reduces heavy metal ions such as chromium, nickel and copper in electroplating wastewater into solid metal precipitates to meet discharge standards. It is also applied for paper bleaching and reduction treatment of chemical waste streams, convenient for on-site dosing without powder dissolution operation.
Synthesis grade sodium borohydride solution is designed for fine chemical and pharmaceutical intermediate reduction reactions. It is used to reduce aldehydes and imine groups in organic synthesis. The ready-to-use liquid form avoids dust hazard and manual dissolution error, suitable for continuous reactor production of agrochemical intermediates and specialty fine chemicals.
Packing
200L HDPE plastic drum. Customized packing available on request.
Delivery & Storage
Store in cool, dry and well ventilated warehouse, keep tightly sealed. Must be separated from acids, oxidants and organic materials. Avoid high temperature, which accelerates decomposition and hydrogen release. Shelf life is 6 months under proper storage. It is dangerous goods shipment with complete export documents.
* Please note that Sodium borohydride NaBH4 CAS 16940-66-2 (powder or granule) belongs to Special Surveillance List chemicals. Please make sure the legal use before inquiring from us. The dual-use import permits will be needed for exports to some countries such as Mexico, Myanmar, Cambodia and Afghanistan etc.
