Mineral salt (calcium, fatty acid)
Identity: Calcium undecylenate
IUPAC name: calcium bis(undec-10-enoate)
Method for the $250 identity, purity and quantity test: ICP-MS metal content, chromatographic assay and identity of the undecylenate, with detection selected for the compound, against a reference standard, with results in 3 to 5 business days.
The USP monograph covers identity by a calcium test, infrared spectroscopy and chromatographic retention time, assay by chromatography, free undecylenic acid by chromatography, loss on drying and particle size by sieving. Full testing to the USP Calcium Undecylenate monograph is available and quoted.
Chromatographic purity and mg per unit by the method matched to the compound, identity against a reference standard. 1 unit.

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 ICP-MS for calcium content and a chromatographic assay for the undecylenate part, with detection selected for the compound. Full testing to the USP Calcium Undecylenate monograph is available and quoted.
Undecylenic acid has almost no UV absorbance, so the lab uses a detection method suited to the compound. The acid is freed from the calcium before it is measured.
Related fatty acids with other chain lengths or double-bond positions can be present from manufacture, and the chromatographic test separates them from undecylenic acid.
Usually a fine white powder, often in foot powders. Powders containing talc or starch are extracted before testing, and the result is reported per gram of product.
