Anhydrous
Anhydrous — Containing no water. Anhydrous conditions are critical during certain peptide synthesis steps to prevent hydrolysis of reactive intermediates.
What Does Anhydrous Mean?
Anhydrous means completely free of water. In peptide synthesis, anhydrous conditions are essential because water competes with the peptide amine for reaction with activated amino acids, reducing coupling efficiency. Anhydrous solvents (DMF, DCM, NMP) and anhydrous TFA are standard in SPPS.
Context
- SPPS solvents: DMF and DCM stored over molecular sieves to maintain anhydrous conditions
- Reagent quality: Anhydrous-grade coupling reagents prevent hydrolysis of activated esters
- Storage: Lyophilized peptides stored in desiccated containers to maintain anhydrous state
