DL-Tyrosine is a racemic mixture of the amino acid tyrosine, with CAS number 556-03-6 and molecular formula C9H11NO3. It is supplied as a white to off-white crystalline powder with a molecular weight of 181.19 g/mol. Unlike its L-enantiomer, which is used in human nutrition, DL-Tyrosine is primarily employed in chemical synthesis, pharmaceutical intermediates, and biochemical research where stereochemical purity is not required.
The product is manufactured through chemical synthesis and typically achieves 99% purity by HPLC. Moisture content is controlled below 0.3%, and heavy metal levels are kept under 5 ppm. It is stable under ambient conditions but hygroscopic, requiring sealed packaging. Standard packaging is in 25kg drums with inner polyethylene lining to prevent moisture ingress. The absence of enantiomeric separation makes it unsuitable for direct human consumption but ideal for industrial applications.
Buyers include pharmaceutical companies synthesizing dopamine analogs, manufacturers of peptide precursors, and research institutions studying enzyme kinetics. The product is shipped under FOB Wuhan or CIF terms, with lead times of 7 to 14 days after payment. Payment is commonly via T/T or L/C. Buyers should request batch-specific assay data, particle size distribution, and residual solvent analysis to ensure suitability for their intended use.
