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.
Norfloxacin is a synthetic broad-spectrum antibacterial drug that is effective against various gram positive and gram negative bacteria. Its major application is in the treatment of urinary tract infections.

Application

Norfloxacin may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and serum samples by high performance liquid chromatography (HPLC) and spectrophotometric methods.

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.

Biochem/physiol Actions

Norfloxacin blocks DNA replication by interfering with an ATP-induced structural transition of DNA complexed with DNA gyrase (topoisomerase).
Mode of action: inhibits bacterial DNA replication
Antimicrobial spectrum: Gram-negative bacteria; less effective against Gram-positive bacteria

Analysis Note

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