Levodopa CAS：59-92-7

First and foremost, Levodopa is a high-purity amino acid derivative pharmaceutical API extracted or chemically synthesized as dopamine precursor. This critical neuroprotective raw material improves motor nerve signal transmission and relieves dyskinesia symptoms. For this reason, pharmaceutical manufacturers, compound drug labs and medical preparation factories widely adopt this standardized active pharmaceutical ingredient for prescription medicine production lines.

To start with, levodopa exists as white to off-white fine crystalline powder with almost no peculiar odor. In addition, it dissolves moderately in hot water and dilute acid solutions, while barely soluble in ethanol, ether and neutral cold water. Meanwhile, light-proof sealed cool storage can effectively prevent oxidation and discoloration. On the contrary, prolonged exposure to light, air and high temperature triggers oxidation, turning the powder dark brown and reducing pharmaceutical potency. Besides that, our finished material meets USP, EP and BP pharmacopoeia standards with HPLC purity above 99%.

We adopt strict pharmaceutical-grade synthesis or natural bean fermentation routes as core feedstock. Firstly, raw intermediate materials go through multi-stage impurity removal and decolorization. Next, directional chiral synthesis or biological fermentation generates pure levodopa monomer. After that, repeated recrystallization, ultra-fine filtration and low-temperature drying refine the finished crystal powder. Furthermore, each batch undergoes strict chiral purity, heavy metal and microbial limit testing. Thus, stable qualified Levodopa is ready for global bulk pharmaceutical shipment.

Compared with low-purity crude intermediates, our levodopa features strict single chiral configuration without toxic enantiomer impurities. In addition, low residual solvent and heavy metal levels fully comply with international pharmacopoeia limits. Moreover, stable crystal form guarantees consistent dissolution rate for tablet and capsule preparations. Meanwhile, fine uniform particle size simplifies mixing during pharmaceutical compounding processes.

For instance, it serves as the core active raw material for Parkinson’s disease oral tablets and sustained-release capsules, alleviating tremor, rigidity and movement slowness.

Blend levodopa with carbidopa and benserazide to manufacture combined dopamine regulator preparations that lower side effects.

Beyond formal drug production, this high-purity crystal is used for neuroscience experimental research and clinical trial compound formulations.
