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 Scopolamine Hydrobromide monograph is available and quoted.
Yes. Scopolamine has an epoxide oxygen that atropine and hyoscyamine lack, so it differs in mass and separates by HPLC.
Scopolamine hydrolyzes to scopine and tropic acid, and can lose water to aposcopolamine. These products appear as separate peaks in the purity profile.
USP material is the trihydrate, with about 12 percent water. The assay basis, as-is or anhydrous, is stated on the report.
