2-Chlorotrityl Chloride Resin
This resin offers exceptional utility in the field of chemical synthesis, particularly for solid-phase peptide synthesis (SPPS) and complex organic molecule construction. Its primary value lies in its unique acid-lability, allowing for the cleavage of synthesized compounds under remarkably mild acidic conditions. This property is critical for preserving sensitive protecting groups such as Boc and tBu, which is essential when preparing protected peptide fragments for convergent synthesis strategies. The resin’s structure also inherently minimizes side reactions like diketopiperazine formation, a common issue in peptide chain elongation, especially for sequences involving proline or cysteine at the C-terminus.
- Benefit from mild acidic cleavage conditions for protected peptide fragments, crucial for the integrity of acid-sensitive functionalities in your synthesized molecules.
- Prevent diketopiperazine formation and minimize racemization during peptide synthesis, ensuring higher purity and yield of your target peptides.
- Leverage its versatility for a wide range of synthetic methodologies, making it a cornerstone in preparing various small organic molecules and complex structures.
- Achieve good loading capacity, enabling efficient attachment of the first building block and contributing to overall higher yields in your synthetic processes.
