Frequently Asked Questions

What is L-Tyrosine USP powder used for?

L-Tyrosine (CAS 60-18-4) is an aromatic amino acid used as a nutritional supplement and flavoring ingredient in food, as a biochemical research reagent in life-science labs, and as a skin- and hair-conditioning and antistatic ingredient in cosmetic formulations. RawSource supplies USP-grade crystalline powder for these industrial and formulation uses.

What foods are high in tyrosine?

Tyrosine occurs naturally in protein-rich foods such as cheese, soy, meat, fish, eggs, and nuts. As a supplier we provide isolated, purified L-Tyrosine USP powder (formula C9H11NO3) for use as a defined ingredient in food and supplement manufacturing rather than as a whole food.

What is the difference between N-Acetyl L-Tyrosine and L-Tyrosine?

N-Acetyl L-Tyrosine (NALT) is the acetylated derivative of L-Tyrosine and carries a different CAS number and solubility profile. This product is plain L-Tyrosine USP (CAS 60-18-4); if you require NALT, specify it on your RFQ as it is a distinct material.

What is the CAS number and HS code for L-Tyrosine?

L-Tyrosine USP powder is CAS 60-18-4, molecular formula C9H11NO3. It classifies under HS heading 2922.50 (amino-acid-phenols and other amino-compounds with oxygen function) for import/export documentation.

What bulk packaging and documentation are available for L-Tyrosine USP?

RawSource ships L-Tyrosine USP powder in bulk industrial packaging (drums and palletized fiber drums) to manufacturers, with USP-grade Certificate of Analysis and SDS provided on request. Request a bulk quote with your target volume and packaging preference for current pricing and lead time.
