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 Doxylamine Succinate monograph is available and quoted.
No. Succinic acid is the counter-ion of the salt and elutes separately. The purity result covers doxylamine and its related compounds, and the assay is reported as doxylamine succinate.
Yes. Doxylamine is often combined with other actives such as pyridoxine, and HPLC separates the two so each can be reported against its label claim.
