No. The $250 test covers identity, purity and quantity by HPLC with UV detection for purity and assay, and LC-MS for identity. Full testing to the USP Alosetron Hydrochloride monograph is available and quoted.
The USP material is the hydrochloride, and the assay is reported on that basis unless you ask for the free base. Tablet strengths are usually stated as alosetron base, so tell us which basis you need.
Most samples are a white to off-white powder or tablets. Tablets are ground and extracted, and the result is reported per tablet or per gram.
