SiSiB® PC5603 is thermally stable and reacts readily with water or alcohols in presece of acids or base to generate highly flammable hydrogen gas.

SiSiB® PC5603 is the hydride source in many selective reductions among which is the reduction of acetals and ketals to ethers. In combination with an alkoxysilane, triethylsilane can bring about the reductive etherification of ketones or aldehydes.

SiSiB® PC5603 is used with TFA in Ionic hydrogenation as an alternative to catalytic hydrogenation.

SiSiB® PC5603 reacts as silyating agent for derivatization of alcohols, phenols etc.
