Antifungal (hydroxypyridinone)
Identity: Ciclopirox
IUPAC name: 6-cyclohexyl-1-hydroxy-4-methylpyridin-2-one
Method for the $250 identity, purity and quantity test: HPLC-UV purity and assay, LC-MS identity, against a reference standard, with results in 3 to 5 business days.
The USP monograph covers identity by infrared spectroscopy, assay by potentiometric titration, related compounds by HPLC, and loss on drying and residue on ignition; the olamine salt monograph adds pH and a monoethanolamine content titration. Full testing to the USP Ciclopirox 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 HPLC-UV for purity and assay, with LC-MS to confirm identity. Full testing to the USP Ciclopirox monograph is available and quoted.
Ciclopirox olamine is the salt of ciclopirox with ethanolamine (monoethanolamine), and it has a higher molecular weight than the free acid. Tell us which form is on the label so the assay is calculated on the right basis.
Ciclopirox is an N-hydroxypyridinone that binds iron and other metal ions. Trace metals in the system can cause tailing peaks, so the method uses conditions that limit metal binding.
Powder, creams, gels, shampoos and nail lacquer solutions can be tested. Topical products need an extraction step before HPLC, and the result is reported as a percentage by weight.
