Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Levetiracetam monograph is available and quoted.
No. Levetiracetam is the S-enantiomer, and its R-enantiomer has the same mass and retention time on a standard column. The monograph measures it by chiral HPLC, which is quoted separately.
Powder, tablets, extended-release tablets and oral solution. Levetiracetam dissolves readily in water, so extraction is simple and the result is reported as percent of label claim.
