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.
Flucytosine is an antimycotic drug that can be effectively utilized against severe Candida and Cryptococcus infections.

Application

Flucytosine may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography 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.

Biochem/physiol Actions

Nucleoside analog that has antifungal activities. 5-FC is deaminated by cytosine deaminase to product 5-fluorouracil, resulting in RNA miscoding. 5-Fluorocytosine inhibits DNA and RNA synthesis and interferes with ribosomal protein synthesis.

Analysis Note

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

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
