Phenylalanyltryptophan

Phenylalanyltryptophan (CAS 24587-41-5), commonly referenced as Phe-Trp in research and procurement contexts, is a dipeptide composed of phenylalanine and tryptophan. It is used as a bioactive building block and reference standard in peptide synthesis.

This compound is essential for pharmaceutical development and nutritional research programs. In pharmaceutical development, Phe-Trp serves as an intermediate in the synthesis of longer bioactive peptide sequences targeting neurological and metabolic pathways.

Biotechnology laboratories use it as an analytical reference standard for HPLC method validation and peptide quantification assays. In food and nutrition research, it is evaluated as a functional peptide component in studies examining bioavailability.

Researchers utilize this dipeptide for examining gut-derived signaling. Formulators working on peptide-based nutraceuticals also source it for small-scale prototype development and stability testing to ensure product efficacy and shelf life.

Phenylalanyltryptophan is supplied as a white to off-white lyophilized powder or crystalline solid. It is available in research-grade and pharmaceutical-grade specifications, with purity levels typically confirmed by HPLC analysis.

Quantities range from milligram-scale reference amounts to gram-scale research batches, depending on supplier capability. The material is handled according to strict quality standards to ensure consistency across various laboratory applications.
