2. Aplicaciones

Fmoc-L-Arg(Pbf)-OH is a critical reagent in solid-phase peptide synthesis (SPPS). Key applications include:

• Building block for introducing arginine residues into peptide chains.
• Protection of arginine side chains during synthesis (Pbf group prevents unwanted reactions).
• Widely used in pharmaceutical research, biotechnology, and academic studies for developing therapeutic peptides.

3. Instrucciones de uso

Step 1: Preparation

Equilibrate the compound to room temperature before use to avoid moisture absorption.

Step 2: Dissolution

Dissolve in dimethylformamide (DMF) or dichloromethane (DCM) at a concentration of 0.1-0.3 M.

Step 3: Coupling Reaction

Use coupling agents like HBTU or HATU (1:1 molar ratio) with a base (e.g., DIPEA) for 30-60 minutes.

Step 4: Deprotection

Remove the Fmoc group with 20% piperidine in DMF. The Pbf group remains intact until final cleavage.
