Ac-Phe-NH2 is N-acetyl-L-phenylalaninamide with an N-acetyl group and C-terminal amide. The blocked termini reduce terminal-charge effects and make the compound useful as a compact model of an internal peptide environment.

Product Information

Application as a Capped Peptide Model

Terminal capping makes Ac-Phe-NH2 more representative of an internal peptide segment than the corresponding free amino acid or uncapped dipeptide. The phenylalanine side chain provides the main product-specific chemical feature for comparative physicochemical or analytical work.

Lot Documentation and Sample Handling

For comparative or quantitative studies, review the lot-specific purity method together with molecular identity data. HPLC purity, mass confirmation and nominal vial mass describe different attributes and should not be treated as equivalent measures of analyte content.

For matched comparative studies, use consistent purity, solvent and concentration across the compound set. Solvent and working concentration should be validated for the intended assay when no product-specific solution data are supplied.

Related capped models can be explored under peptide model compounds.

Frequently Asked Questions

Are both termini blocked?

Yes. The N-terminus is acetylated and the C-terminus is amidated.

Can this material be treated as an ordinary chain-extension reagent?

No. The capped termini make it better suited to model, analytical or assay applications than routine peptide elongation.
