Aromatic Amino Acid L-Tyrosine CAS 60-18-4 | 99% High Purity Food & Pharma Grade L-Tyrosine Global Bulk Supply From Manufacturer

Common Pain Points of Buying L-Tyrosine Overseas | Why Choose Direct Factory L-Tyrosine

Global pharmaceutical manufacturers, food nutrition processors and biotech laboratories often face 4 typical troubles when sourcing L-Tyrosine in bulk, which are top search pain points for international buyers on Google:

1. Fluctuations in batch color difference and purity, leading to repeated formula adjustments and higher production costs;
2. Incomplete export certificates including COA, MSDS and certificate of origin, causing customs clearance delays in EU, US and Southeast Asia;
3. Unstable chemical activity of raw materials, resulting in inconsistent test data in Maillard reaction and pharmaceutical synthesis;
4. Marked-up prices from middlemen, out-of-stock risks in peak seasons and unstable year-round supply chains.

Every batch is tested by HPLC with traceable test reports, perfectly matching long-term standardized mass production for overseas clients.

Core Industrial Advantages of L-Tyrosine

1. Consistent Batch Indicators to Avoid Formula Waste

Produced in fully enclosed dust-free purification workshops. Each batch is strictly tested for color, purity, light transmittance and heavy metal impurities. We eliminate common defects of cheap raw materials such as yellow powder, unstable purity and weak activity, saving clients frequent formula adjustment and finished product loss.

2. Full Set of International Compliance Documents for Smooth Global Customs Clearance

All grades of L-Tyrosine meet global food and pharmaceutical raw material standards. We supply complete export files free of charge: COA, MSDS, certificate of origin and third-party test reports, satisfying import audit standards of the US, EU, Australia, Middle East and Southeast Asian countries to simplify clearance procedures.

3. Multi-Scene Universal Raw Material to Cut Sourcing Costs

Single L-Tyrosine covers three major industries: food, pharmacy and biochemistry. Buyers do not need to cooperate with multiple raw material suppliers, unifying purchasing, warehousing and accounting to reduce communication, logistics and storage costs, ideal for large integrated biotech and food groups.

4. Controllable Chemical Reactivity for High-End Fine Synthesis

With stable active phenolic groups, our L-Tyrosine delivers repeatable results in Maillard flavor reaction, azo color reaction and peptide synthesis, meeting strict production and experiment requirements of pharmaceutical factories, university labs and biotech R&D institutions.

Global Main Industrial Application Fields of L-Tyrosine

1. Pharmaceutical & API Synthesis Industry

Pharma grade L-Tyrosine acts as core raw material for compound amino acid infusions and clinical nutritional formulations, used in supportive preparations for hyperthyroidism, encephalitis and poliomyelitis treatment.

As the synthetic precursor of dopamine, adrenaline, thyroxine and melanin, it is an essential intermediate for peptide hormones, catecholamine drugs and antibiotics, purchased steadily by API manufacturers worldwide.

2. High-End Food & Dietary Supplement Industry

Food grade L-Tyrosine is a compliant natural nutritional fortifier widely applied in sports nutrition shakes and functional dietary supplements.

It generates rich natural aroma via controlled Maillard reaction with saccharides, improving flavor for bakery goods, snacks and processed meat, fully complying with global clean label food production codes.

3. Biochemical Research & Cell Culture

High-purity reagent grade L-Tyrosine is supplied to overseas university labs, third-party testing agencies and biomedical R&D enterprises:
Applied in nitrogen quantification of amino acids, Milon’s colorimetric protein assay, microbial strain cultivation and animal tissue cell medium preparation, serving as standard raw material for basic biochemical experiments.
