Description

General description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Levofloxacin Hemihydrate is a third generation fluoroquinolone antibiotic that is known to inhibit the replication of bacterial DNA by interfering in the activity of DNA gyrase (topoisomerase II) and also during bacterial growth and reproduction.

Application

Levofloxacin Hemihydrate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography and spectrophotometric techniques.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Analysis Note

These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
