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 Deoxycholic Acid monograph is available and quoted.
Bile acids have almost no UV chromophore, so the lab uses a detection method suited to the compound.
Other bile acids, such as cholic acid, and isomers of deoxycholic acid are the usual related compounds. Several share a mass with deoxycholic acid, so chromatographic separation matters.
No. They have the same formula, C24H40O4, but the hydroxyl groups sit in different positions. HPLC retention time tells them apart, even though they have the same mass.
