Description
Catalogue Number853074
Replaces04-12-0187
Brand Family Novabiochem®
Alternate Names
  • N-α-t.-Boc-β-trityl-L-asparagine
Background InformationA trityl-protected derivative which increases the solubility of Asn during the coupling step in SPPS [1]. Its use gives higher yields and lower by-product formation. During the following coupling cycles the temporary side-chain protection is removed.

The product number for this product was previously 04-12-0187.
