IUPAC name: 2-[4-[1-hydroxy-4-[4-[hydroxy(diphenyl)methyl]piperidin-1-yl]butyl]phenyl]-2-methylpropanoic acid;hydrochloride
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, HPLC retention time and a chloride test, assay by HPLC, a named related compound and other organic impurities by HPLC, plus residue on ignition and water content. Full testing to the USP Fexofenadine Hydrochloride 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 and LC-MS for identity. Full testing to the USP Fexofenadine Hydrochloride monograph is available and quoted.
It can. USP allows anhydrous material and hydrate forms, so the monograph includes a water test and the assay is calculated on the anhydrous basis.
Yes. Fexofenadine is the carboxylic acid form of terfenadine, so the two differ in mass by LC-MS and elute at different HPLC retention times.
