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.
Natamycin is a major drug that is utilized in the treatment of fungal keratitis. It is, by far, the only available approved antifungal drug for the said purpose by the U.S. Food and Drug Administration.

Application

Natamycin may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by high-performance liquid chromatography coupled with tandem mass spectrometry (LC−MS/MS).

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

An antifungal polyene macrolide that binds specifically to ergosterol and blocks fungal growth. However, unlike nysatin and filipin, pimaricin does not change the permeability of the plasma membrane

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.
