description
Isomeric purity >99.9%. Building block for the introduction of selenocysteine by SPPS. 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.
