Sodium tetrachloroaurate(III) dihydrate, Premion™, 99.99% (metals basis), Au 49-50%

Description

CAS: 13874-02-7 | AuCl4H4NaO2 | 397.79 g/mol

It is used in chemo-therapeutics. It is employed as a catalyst in the removal of tert-butyl(dimethyl)silyl (TBS) protecting groups. It is selective in the presence of aromatic TBS ethers, aliphatic triisopropylsilyl ethers, aliphatic tert-butyl(diphenyl)silyl ethers, or sterically hindered aliphatic TBS ethers. With excess catalyst, TBS ethers can also be transformed into 4-methoxybenzyl ethers or methyl ethers in one pot.
