Levetiracetam has become a go-to API for formulators targeting epilepsy and beyond. Its unique binding to synaptic vesicle protein 2A (SV2A) sets it apart from traditional sodium-channel blockers, driving demand in both human and veterinary neurology. As patents expire, generic entries are surging, and procurement teams are actively qualifying new suppliers to secure consistent, high-purity material. The compound also shows promise in neuropathic pain and mood disorders, widening its commercial footprint.
This second-generation antiepileptic is a chiral pyrrolidine derivative, synthesized through a multi-step route that demands tight stereochemical control. The (S)-enantiomer is the active form, and regulatory agencies enforce strict limits on the (R)-impurity. Manufacturers must navigate complex crystallization and purification to meet pharmacopeial standards, making supplier selection a critical decision for both quality and cost.
LyvBio supplies Levetiracetam with assay 98.0–102.0% (HPLC) and full documentation, including elemental impurities and residual solvents. Our material is manufactured under cGMP and is available in commercial quantities. Whether you are developing a generic oral solid or exploring new delivery systems, our team supports your technical and regulatory needs with responsive service and reliable supply.
Levetiracetam is a white to off-white crystalline powder, freely soluble in methanol and ethanol, and sparingly soluble in water. It is chemically stable under normal storage conditions, with a molecular weight of 170.21 g/mol. The API is typically milled to a consistent particle size distribution to ensure blend uniformity in tablet and capsule formulations.
Our Levetiracetam is produced via a proprietary synthesis that minimizes chiral impurities and controls particle size. Each batch is tested for assay, related substances, residual solvents, and heavy metals to meet EP, USP, and ICH Q3A/B requirements. The material is non-hygroscopic and compatible with common excipients.
