Fluoroquinolone antibiotic
Identity: Ciprofloxacin
IUPAC name: 1-cyclopropyl-6-fluoro-4-oxo-7-piperazin-1-ylquinoline-3-carboxylic acid
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, residue on ignition, clarity of solution, microbial enumeration and specified microorganisms, loss on drying, sterility, and bacterial endotoxins. Full testing to the USP Ciprofloxacin or Ciprofloxacin 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 quantity and LC-MS for identity. Full testing to the USP Ciprofloxacin or Ciprofloxacin Hydrochloride monograph is available and quoted.
Raw material is often the hydrochloride monohydrate, while some products use the free base. Both give the same ciprofloxacin ion by LC-MS, so ciprofloxacin is measured and converted to the labeled form using molecular weights.
Yes. Fluoroquinolones degrade under light, and ciprofloxacin can lose part of its piperazine ring to form products such as the desethylene compound. Samples should be stored protected from light.
