Description

n-Acetyl-L-Tyrosine is a modified amino acid derivative where an acetyl group is attached to the L-isomer of tyrosine. This chemical modification enhances its stability and bioavailability, making it a crucial intermediate and raw material for advanced synthesis. It is primarily sought after by manufacturers in the pharmaceutical, nutraceutical, and research sectors for developing peptide-based therapeutics, dietary supplements, and biochemical reagents.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of peptide drugs and active pharmaceutical ingredients (APIs).
• Nutraceutical & Dietary Supplements: Used as a precursor in formulations aimed at supporting cognitive function and stress response.
• Biochemical Research: Serves as a standard or reagent in enzymatic studies, metabolic pathway analysis, and proteomics.
• Cosmetic & Personal Care: Incorporated into advanced skincare formulations for its potential role in peptide-based anti-aging products.
• Animal Nutrition: Utilized in premium feed additives to support animal health and development.
