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 with UV detection for purity and assay, and LC-MS for identity. Full testing to the USP Bromocriptine Mesylate monograph is available and quoted.
Yes. Ergot-type alkaloids degrade in light and heat, so samples should be shipped in their original container, protected from light.
The USP article is the mesylate, and the salt adds methanesulfonic acid to the weight. Quantity is reported as bromocriptine mesylate unless you ask for the free base.
Yes. The bromine atom gives a distinctive two-peak isotope pattern in the mass spectrum, which helps confirm identity by LC-MS.
