L-Alanyl-L-tyrosine

L-Alanyl-L-tyrosine (CAS 3061-88-9), commonly referenced as Ala-Tyr in research and procurement contexts, is a dipeptide composed of alanine and tyrosine used as a biochemical building block.

It serves as a reference standard across pharmaceutical and biotechnology supply chains. It supports peptide synthesis workflows and serves as a functional ingredient in specialty nutritional applications.

In pharmaceutical development, Ala-Tyr is used as an intermediate in the synthesis of longer peptide sequences and as a reference compound in analytical method validation for various laboratory protocols.

Biotechnology researchers source it for use in cell culture media optimization, where dipeptide forms of amino acids offer improved stability and solubility over free amino acids in liquid media.

In functional food and nutraceutical formulations, it is incorporated as a bioavailable peptide ingredient targeting amino acid delivery. Its antioxidant activity is linked to the tyrosine residue.

This positions it for evaluation in stabilized formulations requiring oxidative protection. L-Alanyl-L-tyrosine is supplied as a white to off-white crystalline powder for industrial use.

It is available in research-grade and high-purity pharmaceutical-grade specifications, with purity levels typically confirmed by HPLC to ensure compliance with strict internal quality controls.

Packaging ranges from small quantities for laboratory use to bulk formats suited for industrial formulation or manufacturing scale. The material is handled according to rigorous safety standards.
