Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
What impurities are present in Product 156159, Sodium Cyanoborohydride?
One of the by-products of the synthesis reaction is Dimethyl Sulfide. It is also possible that there could be some Borate salts present.
Why is it recommended to store and handle Product 156159, Sodium Cyanoborohydride, under an inert atmosphere?
Sodium Cyanoborohydride is a very hygroscopic material and contact with water or moist air should be avoided. Allowing the material to come into contact with water or moist air may decompose the material and could lead to a violent reaction or explosion due to the release of Hydrogen gas.
What is Product 156159, Sodium Cyanoborohydride, soluble in?
According to Merck Index, 13th Edition, Sodium Cyanoborohydride is soluble in water (212g / 100g solvent), Tetrhydrofuran (37.2g / 100g solvent), and Diglyme (17.6g / 100g solvent). It is also very soluble in Methanol, slightly soluble in Ethanol and Isopropylamine, and insoluble in Ethyl Ether, Benzene, and Hexane.
