How Vanguard tests Fluconazole

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 and HPLC retention time, assay by HPLC, organic impurities by HPLC, and loss on drying and residue on ignition. Full testing to the USP Fluconazole monograph is available and quoted.

What's reported

Purity, as percent of total peak area
Quantity, against the label claim

Questions about Fluconazole testing

Is the $250 test the same as USP monograph testing?

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 Fluconazole monograph is available and quoted.

Why is LC-MS used for fluconazole identity?

Fluconazole has a weak UV chromophore, so LC-MS confirms its mass and tells it apart from related triazole compounds that look similar by UV.

What forms does fluconazole arrive in?

Powder, tablets, capsules and powders for oral suspension. Each form is extracted and the content is reported per unit or per gram.
