Description

DL‑4‑Hydroxyphenyl‑d₄‑alanine‑2,3,3‑d₃ is a heptadeuterated DL‑tyrosine analogue tailored for peptide‑synthesis workflows, providing reliable isotopic incorporation into aromatic residues while remaining fully compatible with standard SPPS coupling and protecting‑group strategies. Its combined ring‑d₄ and side‑chain‑d₃ pattern supports precise mass‑spectrometric tracking of labelled peptides without altering native reactivity.
