description

Isomeric purity >99.9%. Building block for the introduction of selenocysteine by SPPS in the terminal position. Due to difficult coupling of Boc-Sec(Mob), this is an alternative building block for introduction of Sec residue into peptides.

Peptides containing selenocysteine can be cleaved from the resin with simultaneous side-chain deprotection by treatment with 5% (v/v) water, 95% (v/v) trifluoroacetic acid (TFA), 0.4 M 2,2’-dithiobis(5-nitropyridine) (DTNP) for 7 min at 60 °C or 2 h at RT.
