Trityl chloride resins and as 4-methyl- and 4-methoxytrityl derivatives render increased acid lability, making them less favorable for stable attachment of C-terminal carboxylic acid during peptide synthesis.(1)  In SPPS and SPOS, the immobilization of other functionalities like amines, alcohols, hydroxylamines, hydrazines, or thiols are described; e.g. N-α-amino groups and N-ε-amino groups of lysine are used in anchoring protected peptide segments.(2)
