Chemical Properties

WHITE TO CREAM POWDER

Uses

Nα-Boc-D-tryptophan is an N-Boc-protected form of D-Tryptophan (T947205). D-Tryptophan is an unnatural isomer of L-Tryptophan (T947210) and is classified as an essential amino acid. D-Tryptophan has been synthesized as part of some potent Oxytocin (Acetate: O878500) antagonists that treat preterm labour.
