Descripción general

Ergosterol is a biological precursor of Vitamin D2 found in cell membranes of fungi and some protists such as trypanosomes. It is a major sterol found in fungal cell membranes.
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.


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.

Nota de análisis

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

Otras notas

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.
