Sodium borohydride, ACS – CAS 16940-66-2

Sodium borohydride (NaBH4) is the most commonly available borohydride, synthesized by reacting methylborate with sodium hydride in mineral oil; it is employed as a precursor for producing other metal borohydrides; various approaches for qualitative and quantitative monitoring of sodium borohydride have been explained; the potential of NaBH4 to store as well as generate hydrogen for fuel cells has been investigated.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry; this product has been enhanced for energy efficiency.
Sodium borohydride can be used as a reducing agent:
# to prepare saturated alcohols by the reduction of conjugated aldehydes and ketones;
# along with Raney nickel for the reduction of aromatic nitro compounds to arylamines;
# in the synthesis of secondary amines by reductive amination of ketones and aldehydes
in the presence of an acid catalyst;
# in the synthesis of δ and γ lactones by the reduction of cyclic anhydrides ;
# for the chemoselective reduction of N -protected amino acids and peptides to
corresponding alcohols
