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 HPLC-UV for purity and assay and LC-MS for identity. Full testing to the USP Fluoxetine Hydrochloride monograph is available and quoted.
The monograph defines the material as fluoxetine hydrochloride, so purity and assay are normally reported on that basis. A free base figure can be calculated from the two molecular weights if you need it.
Yes. Capsule contents and liquids are extracted and assayed against a fluoxetine hydrochloride reference standard. Give us the label claim so the result can be reported as percent of label.
No. Fluoxetine hydrochloride is a racemic mixture of the R and S forms, and a standard reversed-phase HPLC purity method does not separate them.
