L-phenylalanine

L-Phenylalanine (CAS 63-91-2 ) is an essential amino acid supplied as a pure crystalline ingredient for nutritional, pharmaceutical, and specialty formulation use. Known in the trade as L-Phe and assigned FEMA 3585 , it is a critical raw material.

It serves as the direct biosynthetic precursor to several high-value compounds, including aspartame, making it essential for sweetener and flavor manufacturers. In food and beverage manufacturing, it is the key building block for large-scale production.

Pharmaceutical formulators use it as an active ingredient and synthesis intermediate in amino acid infusion solutions and parenteral nutrition products. It is also utilized extensively in peptide drug manufacturing and specialized medical foods.

Sports nutrition and dietary supplement brands incorporate it into free-form amino acid blends and protein fortification systems. These applications target muscle recovery and metabolic support for high-performance athletes and health-conscious consumers.

Personal care formulators apply it in skin-conditioning and antioxidant-stabilized topical products where amino acid actives are specified. It provides functional benefits in various cosmetic formulations requiring high-purity chemical inputs.

L-Phenylalanine is supplied as a white crystalline powder in both food-grade and pharmaceutical-grade specifications. Recognized quality standards include USP , BP , Ph. Eur. , and FCC , supporting global sourcing.

Standard pack sizes range from kilogram quantities to bulk metric-ton shipments to meet diverse industrial needs. Fermentation-derived material is available to meet clean-label and non-GMO positioning requirements for modern brands.
